Even though we live in Concord, we will drive out to the Antioch location. Less crowded and easier to park in the lot. Also much cleaner than the Concord location. We came in for eggs and almond milk. Was happy to stock up on the smoke detectors and carbon monoxide combo. Saves us a trip to Ace I also adore the room service Jammie's. Excited to see these 2 pack sleep shorts I've been buying the sets in the past- adding these sleep shorts to my sleep rotation Great prices compared to online for these Jammie's read more

Yesterday ,September 16th, 2026 I went to Costco in Antioch to refill gas. I pulled up to the next available pump just to read a hand written note "no premium here". Okay wtf, I drove a circle to another pump and ... the same sticker on the pump. Then I realized that there were many other customers also driving around confused like I was. I finally asked the guard about it and he just said "no premium at this station"! No sorry, no why ... Why not put a sign at the entrance of the station so no fu$$ up at the place? Oh and thanks to the people who voted for this government administration who's causing with the Iran war all this mess to us! read more

I just experienced the worse type of treatment, literally faced discrimination from the hands of a woman at the entrance. Around 3pm today I checked in and found out my membership card just expired, I told the lady, I'll pay at cashier when checking out. She immediately said I can't enter the store. I told her I have renewed my membership many times like that. She immediately said she's calling her manager, I said that's fine I'll wait. To my surprise this woman called and told the manager I REFUSED TO PAY, lying on me while waiting for the manager at the entrance. I got very upset for telling such a lie on me. We left and drove to Concord branch 20 minutes away. I asked one of the manager's at the concord store if costco changed their policy that you can't renew your membership at the cashier checkout, the manager said no that's not true you can still pay at the check out at any location. I was just confused why the woman would embarrass me publicly at the antioch store. I don't want to use race but that's my only conclusion. read more

Great service and amazing selection! I've been coming to this Costco for many years, and it never disappoints. There are always great values and plenty of savings--especially this weekend! I can't wait to see more deals during the holidays. I really love the growing selection of Asian snacks too--it's nice to see more variety each time I visit. Definitely appreciate it! read more

If you wanna go to costco better go to the one in Brentwood, I was at self checkout with 8 items in cart we scanned everything and we wanted to pay with cash last minute we forget we only have cash so we asked for the receipt and go to the other register so we pay with cash and the way the lady ignored us omg she didn't even help us or talked to us the employees are disrespectful to customers a lot. We asked for manager and she helped us finally and solved the situation. Not ever going back here. read more

Costco does not care about you. If you are disabled, sick, old, or fear that you may ,at any point, be unable to pick up your own groceries Costco is not the place for you. Tried to pick up groceries for my elderly sick mother and Costco employees told me she would have to be there herself. No guest pass no way of purchasing groceries and then having a named person pick them up for her. Just pay or leave. Thankfully she did not make the mistake of using their pharmacy or it could have actually cost her her life. If you are disabled, sick, old, or immobile Costco doesn't want you and they don't care about you. read more

This is my second favorite Costco! Customer service is always friendly. They're always stocked up on items. Plenty of parking.

My husband and I just had the BEST experience from the Optical department from an associate by the name of TASHA .We thought she was the Manager !. My husband was only going to purchase 1 pair of glasses ,he end up buying 2 pair! She took her time explaining and listening to all my husband questions and concerns and making sure the center of his vision was centered and marked the glasses for pickup . NOW that is ***** Customer service. Friendly and Knowledgeable consumers ask for Tasha . She the Best That made his birthday in which is today! read more

Costco - Tasha , Superior customer service! - Wholesale Stores Near Me - Antioch, California

Top flight and if you don't like whatever you purchased, Costco ask no questions on your returns.

Very disappointing customer service experience today. The employee who checked me out, Laz B., never greeted me, made no eye contact, and did not ask if I needed anything else or if I would like anything from the food court. Throughout the transaction, he appeared more focused on talking with another employee who was assisting him than on helping the customer in front of him. There was no "thank you" or acknowledgment at the end of the transaction. I expect basic courtesy and professionalism when shopping, and unfortunately, this experience fell far short. I hope management addresses this and reinforces the importance of customer service. read more

It's so funny how when a lady asked me to apply for an executive club membership, I said "no" because I don't come here that often. I've been coming here a lot more and more than what I said to the lady when I first applied for membership years ago. I really love that there is a Costco close to me. This Costco has great selection of items and I always get what I need. The one con about going to Costco is everything is big. What I mean is if I need just a carton of milk it comes in a pack of three. But the price is right. Costco always has great holiday items. Costumer service is ok. I rarely need to ask for help. Unless I go to Optical or their foodcourt area and then when you check out. That's the only real reaction with employees at Costco. read more

I had an appt. on 1/14/26 in the Tire dept. to have my tires rotated at no cost on my Toyota. Shortly after I received a call and told I had two stripped lug nuts and my car was unsafe to drive and recommended I have my truck towed to a mechanic. He also put white chock on my seized studs identifying them. Then drove to Les Schwab in Oakley they quoted $166 and $31 for my Costco tires to be rotated. At the end they only charged me $31 the lug nuts were fine they had no issues. Thank god Les Schwab knows what they are doing and didn't fix and charge me. Never going back to Costco for tires. read more

I booked an appointment to have my tires replaced. When arrival, just park on the tire space for customers. The staff got my information and provided an estimate of 1 hour and 15 mins. My wife and I shopped around to kill time for a bit. When we were at the register, the lady scanned my membership and told us we are eligible for a 2% discount since we moved to Oakley. We just need to update our address at the membership counter. I was really surprised and didn't knew at all. After everything was done in about an hour, we waiting at the tire shop. One of the staff came and said the car was ready which was pretty quick than the estimated time. What I liked was how the staff done an amazing job explaining everything in detail. read more

So as friends, family and Co-Workers (Yeah I am talking about you) will attest we have a obsession with Costco. So much so we have a set of Costco Rules we live by (after the review). This is your typical Costco and it flows in a clockwise direction from the entrance. You have your typical array of electronics and season items int he front and center and work you way back to the meat and freezer sections As I stated in my review of the the Mountain View location, we do have some rules to help keep our obsession under control: 1) NEVER EVER go in hungry. That 25 gallons of dill pickle chips is much easier to resist on a full stomach.... true story there. 2) Avoid the free samples. People seem to lose their minds with this stuff. They abandon carts with crying babies, block isles, etc all to get that tiny portion of hummus. I have been shoved aside by someone desperate to get a free piece of cheese. Honestly I have seen more dignity from actual starving people in a disaster zone but I digress. 3) Avoid the weekends like the plague. 4) See #1 5) Go often. Costco uses alot of psychology and the fear of missing out is one of them. Odd items you must have pop up then go never to return. I CAN'T MISS OUT AGGGGGGG 6) Know your codes: At costco any price ending in 0.97 means it has been marked down. Any price that is not a 0.99 or .97 such as say 0.49 means it has a manufacturers discount. and price with an * aka "The Death Star" on it means its done and will not be reordered so stock up. If it ends in a .00 or a 0.88 a manager has reduced the price at that location to clear it out. 7) When in an unfamiliar city head to the Costco. They always stock local items you can't find at yours (like two pounds of single origin Kona coffee for 30.00 at the Kilaua / Kona store etc.) and have cheap gas. (Same on Kauai) read more

It's Costco, what do people expect? When I had signed up, it was quick and easy! I guess only negative was the service on my phone so I had to get on their WiFi lol. Shopping there? The selection is crazy. Huge variety, bang for your buck if you're shopping for a family. Samples? Sheesh, I'll be back for thirds. Yes, there are insanely long lines at times, depending on when you go, but that is expected! The staff? They are all very helpful and they are everywhere, you can't not find one if you need assistance. Prices are good, lines up with today's value on things, but definitely a bit cheaper if you think about it. Clothes? SUPER cheap in price, but pretty good quality. Hungry after all that shopping and walking around? The food court is cheap too! $2 for a huge slice of pizza, or a few bucks for a chicken bake, or even $10 for a whole XL pizza; that's AMAZING. You can not beat that anywhere. Not only is it cheap, but the flavor is great, too! By the looks of it, if Costco keeps it up, I'll probably just be a lifetime member lol, take my money Costco!!! read more

I really only come to COSTCO for the food. If you are short on money, or trying to get a quick bite, this is the spot. You don't need their membership in order to eat at their food court. COSTCO is well known for that hot dog value: $1.50 for a hot dog AND a drink! You could never beat that. Pizza is $1.99, and the slice is generous and delicious. I do have a membership I had been given, but I don't shop here because it's not worth it for me. In my opinion, COSTCO is great to buy in bundles. Perfect for families and numerous people for a long time. Since I live alone, I don't need to purchase these bundles, that are naturally more expensive But COSTCO is a winner, and it always stay busy. The one here in Pittsburg is full of deals, with electronics, glasses and numerous things to look at. Parking is big, so you'll be okay to at least get a spot read more

Yesterday I had to have my Costco Membership Card checked 3 times before leaving! Once as I entered, Secondly, when I merely entered the line to go to the cashier, and thirdly at the cashier! My God are you for real! This is too much checking Come on Costco read more

I've been a loyal Costco customer for years, and every visit continues to exceed my expectations. The staff is always helpful and quick to assist with any questions I have. The quality of everything I purchase--from groceries to electronics--is consistently excellent. As for value, Costco offers such amazing deals on bulk items and exclusive brands that it's hard to find better savings anywhere else. I always leave feeling like I got a great deal, and I wouldn't shop anywhere else for my household needs! read more

SELF-CHECKOUT: The Costco worker scans your items instead of the you scanning the items yourself. FOOD COURT: All food from Food Court have to pay tax. - Hot Dog & Soda - $1.50 - Pepperoni or Cheese pizza - $1.99 per slice - Whole pizza (Pepperoni or Cheese) - $9.99 - Chocolate Chip Cookie $2.49 When the worker handed me the cookie, it was warm like out of the oven. I ate a piece of cookie when it was warm which tasted good but then I ate the rest later when the cookie cooled down and to me it tasted better when it cooled down than when it was warm. - Latte $2.99 It was good. It was not too sweet. To all Costcos: It'll be better if you have one line for customers to wait for the next available window for picking up snack purchases from the Food Court. Many times, no matter which line I stand in, is the worst line to wait. It'll be more fair for customers, if there is only one line to wait for the next window. read more

Rude workers pretty much told me the store was closing so I needed to hurry up and the store was still open people still at the register!

I went to Costco to buy a garage fridge and shelves. Almost $1000 of merchandise. The cashier didn't want to ring me up. Called someone in front of me. She refused to allow me to purchase the warranty. No one would help us load the truck. All including the cashier just behaved like I didn't exist or was nothing. Someone came over and didn't ask what was happening before addressing me disrespectfully. If I didn't need my friend and handyman's help, I would have left without purchasing. It's amazing people are still behaving this way in this climate and economy. read more

Another five star review! There's a reason people love Costco! We had a great experience today, from the door checkers, to the sample servers, to the cashier, to the food court server! The store was clean, the air was cool, and the variety of products is always second to none! I was provided a chip sample from a bubbly lady who was excitedly offering the samples and calling "Step up to my booth and have some chips today!" She was so cute, I had to try some! And they were delicious! Lauren was my food court server today, and she was lovely! A real people person! Despite being very busy, she took the time to provide full service, including offering onions for the hotdogs, offering a lid for the ice cream, and asking how my day was going! The door checker was a tall younger gentleman who seemed polite and upbeat. He appeared to take pride in his work and that was refreshing! read more

This isn't my normal Costco, but a change in plans meant I had to come here the day before Thanksgiving. Big crowds but no crazy customers and adequate staff to check everyone out.

I am a pretty big fan of Costco or well I thought I was. We have been looking into the Traeger's, a friend informed me that I should look into the Costco Events and buy at the Costco location that is holding the event because the Traeger 620 was $799. The event was at the Antioch Warehouse. I live in Vallejo; I work in Walnut Creek. I passed on two Costco locations (Concord and Vallejo) to visit this "event". I get there and the sign on the Traeger 620 now says $899. I end up paying $978.74 after tax. I return to my work in Walnut Creek and tell my friend Martin whom had made the recommendation to not only buy the Traeger but to also go to the sales event as the price was better. We happened to be ordering lunch for the Dealership I work for at Costco in Concord. Martin went to pick up our food. I had told him about the $100 price increase and he was a little shocked so he took the time to go look for them at the Concord location. What do you know, they are there for $799. These sort of price inconsistencies are unprofessional and cause your members to LOSE TRUST. I never thought I had to price shop Costco, let alone one Costco to the next. Shame on you!!! I cancelled my first order and had to go pick up the other one in Concord a complete waste of my morning. HIGHLY DISAPOINTED! TRANSPERANCY IN BUSINESS MAINTAINS YOUR CUSTOMER LOYALTY AND FOLLOWING. This was far from transparent! Let me also be clear, the only reason you got two stars after trying to rip me off is because the gentleman working the booth was friendly. read more

I have been an Executive Business member since Costco's inception and even when it first started over in Martinez over in CC county. Sooo a long time! Lately, I have been disappointed in Costco and trying to think of I can justify the 180.00 ( 120. Executive and 60. adding employees) which I just paid for membership renewal. The new bag of rice was filled with little white worms- eeeewww! And they accepted the return as I went right back, and they knew the rice as they had others return it too! So it was a problem they obviously knew about! I also saw one bag that had a corner gnawed on and open and when I looked to the side I see a bunch of mouse traps that were set off already!!!! Ewwwww! Now Costco is know for their good beef and the only one this Dr was saying that checks for Jakob Crutzfeld ( form of mad cow disease). I overheard 2 doctors talking about it- idk if it is really true but I only bought beef from Costco after that lol! I never had a problem until today and I like Costco's usually fresh meat. The ground beef they told us was freshly ground and just put out as we were waiting for it to come out. Date stated packed 11/16/23 but sell by date was 11/17/23 I noticed afterwards( one day after?). Every single package was red meat in the outside but the ground beef inside was a sickly brown! It looked like the old butcher truck of mixing the old meat with the fresh meat covering it in a very thin layer! I spent 120.00 plus in ground beef to pack away for the winter( I package it into smaller freezer bags for a big family). I took pictures for proof and called the Costco manager. First, I was told by the first person it is perfectly normal to be brown on the inside! I told her it browns due to oxygen gets to it and oxidizes which turns it brown. So if fresh why didn't the oxygen get to the outer layer and it was red but how did it get to the inner layer only? She was quiet and handed the call to the manager which said it was impossible because it is grounded and they are known for fresh meat! I said I thought so too since I was waiting for the packages that came out in front of me! Anyway, I have to take the 35 packages I formed out of 4 big back packs at 30.00 approx each ( just in case they did not return my money- not wasting it then) today and hours worth of work all back despite having pictures to show each package! Waste of my time on so many fronts and my money. And each of my grocery bills run from 300-500. each and I go 2-3 times a month( big family and main grocery store I go to)- so I am disappointed. And I'm disappointed by the manager like didn't believe it could happen like basically inferring I must be lying! And they could check my account I never returned any meat before and bought plenty! I did return the rice bag though with worms! So this is a warning for ALL Costco members to check their foods! I forgot to mention their corn also spoiled sometimes with mold on the ends of the cob which you can't see til you open it!!! And for some reason their milk seems to spoil quickly these days! COSTCO you have to do BETTER!!! Just lately noticing these problems-never before! Updated to add: Costco did refund my money at least. So good about that. The staff at the counter was great and helpful and not like the manager. read more

Unpopular opinion: I prefer this Costco over the brand new one in Brentwood. Brentwood has a weird layout and the food court situation is a nightmare. I came here on a Sunday around 12pm and it was not busy at all! I even got a good parking spot. They still had eggs. Food court queue was short. Honestly even though Brentwood is closer, I'm prioritizing coming to Antioch instead. read more
