Scott at the Antioch tire center treated us like royalty! He loaded 6 huge and heavy golf cart batteries onto a cart for us AND then pushed this cart out to our truck and loaded them up for us! Just awesome service and he refused our cash tip. I guess tips aren't allowed at Costco. Thank you Scott. read more

A few months ago my wife, whom I admit is not an expert sea good buyer, bought two bags of mussels. That same evening is was preparing to cook them and noticed most of them were open and smelled horrible. I returned the next day with the mussels and asked for a refund, I was told by the seafood dept. That they were ok and supposed to smell that way. I set the mussels down and left with no refund. Yesterday I bought a nice looking flounder filet and again, opened it when I got home, smells sour and very fishy, 20 bucks right in the garbage. Apparently the seafood dept. can't keep it cold enough or move it fast enough, either way, I will never buy seafood from here again. read more

The supervisors at this location are uneducated, immature & lacking in any mgmt. or customer service skills. However, it shouldn't be too much of a surprise I guess. As per Costco policy, their promotions are based solely on seniority rather than merit or qualifications. The cashiers here work hard... but how effective can they be at keeping down lines when the supervisors are incompetent, ineffective & mostly absent? This parking lot in particular is a warzone. My heart goes out to the staff outside pushing carts... since there are a million crazies speeding around, all fighting for spaces up front that are taken anyway. Maybe the walk from a parking space farther back would result in a heart attack for the average Antioch resident, I don't know. Some shoppers don't have time to fight for these coveted spaces though, so they just park up on the sidewalk and leave their hazards on. On your way in, you might notice several dogs panting heavily in their cars, having been left there by their owners with the windows rolled up almost all the way. Oh well... not like it's too hot in Antioch during the summer time. If you need to shop at Costco, there's also a location in Concord with short lines & supervisors who will go out of there way to help you. The Concord store is also kept much cleaner. I wonder, why are they so much more helpful in Concord? read more

Costco rips Antioch residents off on gas price. Costco sells gas at all their Bay Area residence way cheaper than Antioch people get their gas for 10 miles away from Antioch in Concord Cosco sells their gas $.15 per gallon cheaper than they sell the gas to people in Antioch. That is unfair since we all pay the high price for a membership it should be equal prices all the across-the-board read more

I had wonderful customer service last night at the Antioch Costco. I won't go into the details, but all 3 of the employees that helped me were kind and courteous and helpful, and worked to ultimately be able to resolve my situation. Thank you! read more

Relatively new building with plenty of parking and convenient self checkout line. Isles are clean and this store is generally less crowded than other warehouses in SF Bay Area. Items selection reflects local area, with less gourmet & fine quality food items, and more products for newly constructed houses in Antioch/Brentwood area. Staff is friendly and more accommodating, since this store appear to be less busy than other Costco's. Lines move fast & self checkout helps to speed up process as well. read more

As with most things, I tend to procrastinate and that's exactly what happened as I shopped for my new flat-panel. Costco has a rather large selection of HDTVs and offer advantages over purchasing from Best Buy. For example, Costco offers a two-year complimentary warranty in addition to whatever manufacturer warranty is included with your television. As the Super Bowl steadily approaches, its one of the best times to purchase a new television as manufacturers offer incentives and instant rebates. I researched a new set for weeks and almost went ahead with a purchase back in December, but hesitated as it wasn't exactly what I wanted. Fast forward to last week and Vizio had some amazing deals at Costco with instant rebates. I visited my local Costco (Richmond) and the set had all the features I wanted. I made a mental note to come back later in the week to purchase the set and wasn't worried about their stock because I saw a pallet full of them. Well, the day before the instant rebate expired, I went down to Costco and to my surprise they were sold out. I was pissed at myself for waiting this long. An employee checked stock at surrounding stores and I was on my way to Concord as they had six in stock. I made it to the Concord store and the warehouse was jammed packed with shoppers. I find the display model and ask for some assistance and to my surprise, they were SOLD OUT as well. Another employee did me the favor of running a search of inventory and found a supply at the Antioch store and made a phone call and placed one on hold for me. I made my way to Antioch and my first impressions were how nice the store was. The Costco was not busy, parking was plenty, and the warehouse seemed so much different than other Costco's. Within five minutes, I found my flat-panel, the price was the same, and I was in line with my new TV. I didn't make the effort to find an employee and get my set that was on hold, as it would be put back on the floor anyways. The lines were non-existent and Liz was checking me out and I was forking over $560 for my new flat-panel. Although, I had to visit three different stores, that's no one's fault but my own. Nevertheless, I found the Antioch Costco to be a gem for the people of Antioch and one of my best Costco experiences to date. read more

Stay out of Ernesto's line. He's too busy playing Rico Suave with his helper to ring you up for all your items. They expect you to go back and "handle" it rather than have someone help you. No, you can HAVE it. I just waited in line 20 minutes. I'm not going back there. read more

I actually like this Costco a lot as its huge with ample parking, super clean inside and out, and carries a ton of goodies along with the regular Costco staples I always buy. Food court is really clean as well and kept far enough away from check out lines to not create a huge cluster mess. read more

I'm torn on this one because I have received mixed service at this location. I guess it's really not the people that work here more-so the people that shop here. I really don't mind paying the yearly membership fee because they have great products in quantities that actually help me save gas! I really have a problem though with going down almost every aisle and coming in contact with either stupid, rude or oblivious people. Like I said before the products are great, the service is mixed but when it all comes down to it the stress of shopping with these idiots drives the stake into heart. Sorry Costco, wish you could keep stupid, rude and oblivious people out of your store. read more

Costco is one of my favorite all-purpose stores to shop at. I don't have a membership, but I always come with my parents and I can get lost in there for hours without noticing. Costco has a great marketing strategy and continues to deliver quality bulk products to its eager customers. I also appreciate the sampling they do for most of their products. It truly does work because we've purchased items right after giving them a try. I still remember the days before the remodel of this wholesaler. And the entire store was like flipped to the other side. Since then, the gas station has been added - which I believe has the greatest prices on gas. And the food court is now inside. Parking gets very crowded...almost everyday. But that won't stop us. Hopefully they decide to build one in my city! read more

Who doesn't love Costco ?!?! Although we hardly see any free samples stands anymore the place is still the same. Great choices and large variety of things. Not to mention there awesome food court !! If you haven't tried it yet I highly recommend the churro's. The chicken bake taste amazing too. Can't never go wrong with a little snack for the car ride home lol read more

This Costco is pretty crowded, it has tons of parking but still unless you are looking to wait like a vulture for a closer spot just take one further out. You'll need the walk after all the free samples anyways. The staff here is always friendly, from the door check, the sample people, random staff and checkers - everyone is fairly friendly, attentive and quick to help. Had one weird checker but I'm not going to let her spoil the goodness of the bunch. This place is clean, like super clean. From the parking lot, bathrooms, isles . . . . everything. It feels just like a place that serves/sells foods should. Good wine selection, hot little chickens, a large clothing selection (got a Lucky Brand pair of pants for 20 here), nice food section as the front and well just a large selection of everything in bulk. I highly recommend this Costco over others - new, nice, clean, good service and great selection. read more

Love it here. Every time i go i end up going broke but its fine because you get your moneys worth !

I had my husband swing by to grab pizza from the cafe. He went to the window to order. 10, 15, 20 minutes go by. All the other customers are served over and over...finally 30 mins my husband goes up and asked why it's been 30 mins already... The lady goes Oh, and get the boxed pizza off the top...our pizza was done the whole time! My husband said he'll never go to the cafe again. read more

Shame on Costco Antioch, Ca for during the covid handing out unwrapped paper straws. A worker with gloves picks them up and hands them to you. My work at the hospital had wrapped paper straws so I know they can get them. This was my first time going to Costco since covid. I brought my own bags, the lady at the door screamed at me, NO BAGS, I wanted to ask if I could just keep them in my cart and not use, but she was screaming so loud she didnt hear i wish i had got het name. Otherwise things went smooth read more

Buy the Goodyear Wiper Blades from Costco. They are of great quality.. and a good price of 7.99 plus tax for each blade! Woohooo! :-) I previously had the cheap wiper blades from Kragen and they warped - I just had them for 3 months (from the heat here in the East Bay). read more

What isn't there to love at Costco? Right!!!! I love Costco, Jeremy and I are there at least twice a week. Why do we prefer to Costco? Because they have the best priced organics. They don't have the best variety but there is always something new to try. This Costco is like all the others, but I will give a shout out to their customer service staff. I went to this particular Costco because I was visiting my friend Debbie & Marty. Boy did they go in at Costco, three carts later we were at the checkout. Martin's membership card was declined. Rather than making it a problem for the customer, the cashier called over someone to help and they took the card to the computer and got things squared away. By the time the clerk had rung up their purchases, the issue was resolved and all Marty had to do was stop at the Customer Service counter for his new card. And of course on the way out the door we had to stop for something to eat. I had the polish dog which for $1.50 comes with a soda. Where else can you eat lunch for $1.50, no place people. Give Costco a try, just don't make the mistake of getting carried away with all the great deal and spend your rent money. read more

Whenever I need film processed quickly, I head to the Antioch Costco. They honor requests to add white borders to your prints and can do both glossy or lustre (matte). I've had no problems with typical color film and C-41 black and white film... However, they didn't seem comfortable with cross-processing slide film the one time I asked. And even though they aren't always the most convenient option, I totally appreciate the self-checkout lanes. If you're lucky, other like-minded, low-volume shoppers will speedily march through with you. read more

Went here yesterday because I received a Costco gift card. Called to make sure I could use it without a membership. Was told over the phone that all I to get was a one pass....when I got there was told I did not need pass and I could shop but I would have to use all the money on the gift card... store was packed as expected and went in to get certain items of course I came out with more than I needed. Checkout person was training a young lady and she kept asking for Costco card finally I ignored her ass and the guy said she had a gift card she died by need one we just call out for a 99 and he yelled that shit hella loud as if I was stealing something how embarrassing.... not convinced I need a membership. read more

This rating is for the tires department. If I had a choice of not giving them a star I would not give them any. My bad experience with them happened about a week ago. I got a flat tire the day before. I brought in my 2000 Honda Odyssey the next day. I walked in and asked if they can take a look at my tire if its repairable or not. If not, I would purchase a brand new tire from Costco but they did not even want to deal with me just because I did not purchase the tire from them before. The least Costco could have done is just inspect my tire if it was repairable or not. If it was repairable, I could have taken the tire to another place to get it repaired. America's Tire Co. is where I took my tire to get inspected and ends up I had to buy a new tire. I could have done business with Costco but instead I got a great deal through America's Tire Co. in Brentwood. read more

Did you know you can buy a house, disney / vacation tickets, insurance, a car all with affiliations of costco?! lol.. Anyway, the place isn't amazing but it has good selections of stuff. I personally am not a Costco shopper but love the fact that their gas is MEGA CHEAP compared to everywhere else. It was like $4.14 for regular yesterday. (haha, times have changed, $4 is cheap gas now). Remember that there is only unleaded and premium, (87 & 91), non of the mid-grade stuff (89). read more

I always come to this Costco, no complaints. But today I'm only writing a review because the baker Ernesto was of great help. He helped me with a last minute cake order I needed, very kind hardworking man. 5 star customer service! read more

fast lines, friendly staff .. I just hate that they only carry certain products for a minimal period or move them and make them hard to find. Probably a good sales tactic because then your forced to search the store for what your looking for and end up buying things you weren't even there to get. read more

Been shopping here for about four years. Store is tidy and items are organized nicely. Unfortunately, the customer service from the cashiers range from mediocre to horrible. They act unprofessionally by carrying personal conversations with their coworkers while doing their job. Makes me wonder if their job is easy enough to ring me up while having a conversation on who they're dating this weekend, then they have too many workers at the register area and not enough throughout the rest of the store to help customers find things or answer questions. read more

They always have wedding prices on items if they have one on it in the 1st place. Horrible customer service. I swear it's like they don't know what they are doing. 1st I get pressured to upgrade my membership even though i CLEARLY stated i didn't want to. Then on my next trip i decided to purchase an item i seen my last trip. They are out and tell me that they have none on order and the closest place is Tracy. They have plenty over 65 of them, so no need to stock check. Off to Tracy i go. Only to be told, they are out. The employee must have seen the repair center. Asked if they could put them aside for me when they come in. Told they can't help me. Wasted time wasted gas in my truck. Ten to be told it's your fault for not calling ahead? Have you ever tried to call into this store? Forget about it, you can't talk to a person. It's beyond frustrating! read more

There are some things here that are great, other things not impressive at all. Most of their everyday, shelf items are nothing special. They make you buy in bulk but you don't really save any money at all. We compared prices on a few bulk items at Costco to the bulk section at Lucky (when it was still around) and they were the same price. So you're forced to buy huge quantities of stuff but don't benefit in price compared to other stores--I always that that was the whole point of Costco but it appears they've digressed from that marketing strategy. They do have seasonal specials that are awesome. Massive, extra-large dog beds for $20! I've bought close to a dozen of these over the years. Though I've noticed that the prices have crept up. I still consider Costco the go-to place for dog beds though. Their return policy is probably the most incredible one in the world. I bought a memory foam bed once and while it was great for the first couple of months, a few months after that it started hurting my back, so I returned it for a full refund. Costco online is also a great place to buy a bed because they'll pick it up for free if you want to return it -- although I'm sure the price is increased a bit to compensate for that. Their produce is surprisingly visually appealing. By that I mean they look fresh and huge and perfect. But taste-wise, sometimes it's hit or miss. I've had fabulous produce from them, as well as produce that didn't compare even close to the Farmer's Market. I was shocked at how cheap some of their produce is every day (ie. clamshell of prewashed organic salad greens), yet a lot of things seemed pricey. Seafood always looks fabulous. I always wonder about where they get their meats & produce though. I mean, do they care about how the meat is raised, what hormones or genetically modifying chemicals are used? I suspect not but then, I suspect most supermarkets don't either. Which is why I prefer to buy my fresh foods from places like Trader Joe's and Raleys. I like their selection of prepared foods. Clam chowder, chinese chicken salad, so yum! And all those sample tables are awesome. Who doesn't like free samples, but they really do get me to buy things I would've never considered buying so it's great to be able to try new things. I love their pharmacy. Prices are so much cheaper than anywhere else if you don't have insurance. I get my dogs' meds here (or at Costco online). I think they need to have a separate checkout counter for those paying checks. Because those checkbook people take FOREVER, plus ten minutes. It was actually one particularly long wait in a line behind several check writers that made me give up Costco. 20 minutes in line for 5 items didn't seem worth it. And I am always unhappily surprised at how much my bill ends up being for just a few items. I used to have a child-like delight in their fast food stand, but now I think their hot dogs, pizza, and wraps are actually pretty disgusting so that's no longer a draw. But the cheap sodas still are. Overall, the primary reason we ever go here now to pick up something from the pharmacy or on the very rare occasion when there is something very specific that we can only get from Costco. While we're there, we'll shop for other stuff but we no longer make it a point to go to Costco in general. Lines too long (unless you happen to go when it's less crowded), and most products are not particularly a good enough deal to make it worth it. But sometimes they'll have something that does make it worth it. read more

Best Costco around but that is my bias opinion. I have been to a few other Costco and this one has the best layout and I think this might be the one of biggest Costco around. We spend almost a few grand every visit for the business every 2 weeks and by now the employees know us. Food court is always packed. Don't forget to buy a hotdog and a drink since everyone seems gravitate towards snacks after shopping. Employees are friendly and aisles are kept clean for the most part. Get your shopping done a few days before any holidays or you will get stuck in line for a while. read more

My husband and I come here to get baby things for the most part. You would think you are saving money but it's hard to see that when you have 5 items in your cart ringing up to $100. Samples are always fun to try! They can have some good deals, just remember to utilize your coupon book! Can't go wrong with a quick hot dog and soda for less than 2 bucks. read more

It's a Costco.. what's not to love about it? I love the fact that they rebuilt this new one across the parking lot of the old Costco and added a gas station. I always come here for gas now. They have great service and all of the employees are very friendly and take time to chit-chat with you. The food court is now located inside the building right on the other side of the cashiers. So after paying, you can immediately head over to get some cheap food. This Costco also has self-checkout lanes (: However these lanes do not allow the use of gift cards.. so watch out for that. read more

I appreciate that this Costco is a standalone, with a gas station and tire repair. Not all Costco locations have these extras, mind you. I also appreciate that they are adding more organic produce at this location. Staff is always friendly and many have been working here for upwards of 15 years, and enjoy their jobs (these words coming from their own lips). It can easily get jam packed but the lines move fast. All in all this Costco is good to have around locally. read more

I used to work at this Costco and hated every minute of it (seasonal). Now I go here to eat at the food court. ! BTW, if you do not have a membership, you can still use the pharmacy AND you can also buy alcohol there (with cash ONLY) as long as you go to guest services and ask for an alcohol day pass... You MUST bring cash and ask for the day pass at customer service. In the meantime, I'm gonna get me a Polish dog and soda! YUM! read more

Great Costco. They are very efficient on moving their lines and i always get very good customer service. Not giving them a 5 because I do park on the side of the facility where there is less traffic (i have a fear of getting hit by a car backing out of a stall. Especially with a small child) and the employees seem to smoke in that area. They should smoke in the loading area where customers are sure not to go. But you pass them even when your getting a cart. Most employees hide their cigarettes to avoid the smoke from contacting us (which is sweet) but they should not be smoking there. read more

This Costco does not sell the Cinemark tickets and certain items that I used to buy in Sunnyvale. In addition, their rotisserie chicken is a bit too salty for me. At least, the gas is cheap here. Luckily, I live pretty close this Costco. read more

I like Costco Wholesale, having also worked at this location and now working for the competition it's nice to see the similarities and the differences between here and my place of employment. The food court is the most visited place in my visits to Costco, like the Costco Food Court reguardless of location beats the one at my job (Sam's Club) the Brisket Sandwich and Chicken Bakes are my favorite things on the menu, like what can I say, I like to eat! But to move on to the important stuff as food isn't.... The service here is always amazing, always enough cashiers and they are prompt and fadt and very accurate, thats something as a customer that I appreciate, no one wants to wait in line all day when they want to home happy and rest the demos off! The grounds are always clean and the carts are always well stocked, that's something I really appreciate, appearance is everything and is a reflection of your business and they nailed it on the coffin here everytime I visit. I like the variation on products offered here as compared to where I work. Mostly everything is sold in bulk here, it's a wholesale store and that's to be expected, but, Sam's Club isn't all bulk and sometimes you may not need things in a major quantity which does brings prices down....but that's a company thing and not a individual store thing. I usually find things here I like that my store doesn't carry, like they have a shrimp wonton bowl sold in the refrigerated section which is dynamite and they still sell Lactade Lactose Free Milk in the two big cartons verses my store that stopped selling it. Select things here keeps me a customer. In conclusion.... Costco is a great company and have great selections for families, businesses ect. My only gripe with this location is sometimes there is way to much going on at times (mostly with the demos) and it makes it difficult to navigate especially if you're trying to for the most part be in and out. Other than that totally worth getting a membership! read more

The Costco store itself I don't have a problem with. It's the auto shop/tire shop that is very frustrating. They don't have a system in place for getting the customers in. They say it's first come first serve basis. People get here early, and I mean very early. The tire shop opens at 10 am and people start coming in at 9 am!!! So I get here at 9:15 and there are 5 cars already waiting. 7 more cars drive in, they all get out of their cars and made a line. We, the ones that have been here earlier stay in our cars and get to the line after. So it seems, you can get here at 9:30 or even later, make a line and you can be seen first!!!! This is just such poor system that they have. Now the wait is 2-3 hrs whereas the ones that got here later are out in 45 minutes!!! I guess I need to speak to the manager about this!!! read more

I highly recommend Costco tire service esp Victor who went above and beyond to help us out so we can get home safe. We were visiting Antioch from LA for 2 days and saw our tire was slashed and unfortunately the tire we have is already discontinued. He got us 2 new tires for the price of one (thru warranty), installed and ready in 45 minutes. What an excellent service we received from Victor and Costco is lucky to have an employee like him. read more

Ok just finished for the last time fighting with an umbrella for the patio I purchased $500.00 end of last summer another piece of junk. Already falling appart after being properly stored for the winter. I ended up getting tangled up in the rope falling down and injuring my arm and shoulder on the fall. Costco you have lost a customer and possibly more. read more

So much better then the Danville location. It's huge and very bright. The self check out can sometimes be screwy, but most of the time is great for a small shopping trip. read more

Came here today for my free tire rotation/balance, and also to have them check on a bad tire pressure sensor. Logan waited on us, brought the tire sensor gage out to my car only to find out 2 of them were bad. Luckily they had them in stock, so I dropped the car off and came back right before closing. Logan met us out front, and gave me the paid invoice and my key. The entire transaction was quick and easy, and Logan was very helpful. read more
