My purse was stolen in March and the crooks knew just where to go. Over the course of three days they wrote not 1 but 2 bad checks. It is now July and I am still dealing with the aftermath of this. How is it that I can verify funds on my iphone as a small business person, yet a huge company like Costco still takes bad checks in 2013! read more

Darrio our Costco cashier was fabulous! He was just perfect! The best when it came to taking care of my groceries! He was fast and efficient. Give this man a raise! Also, terrific smile as well read more

Location is good and people are friendly. It's clean and well organized. Their meats are over grade A which is really good! I love their sample booths! read more

Rude employee at check. I won't mention any names but she was didn't allow me to use my credit card which I always use to pay with. She said it was because my wife and I have different last names. She was hella slow maybe because she gives people a hard time. She told me it was policy but why is that I have always paid with it in the past. They should have told me from day one. I feel like canceling my membership. read more

I love costco!! Its always nice to save money and buy in bulk. Came in last weekend and dropped almost 500 bucks.. Guess its true what they say. "Costco 500 club" Clean store, friendly staff. Seems like everywhere we went someone was asking if we needed help. It was weird the people shopping were rude! So rude! We had 2 people hit our cart and then while waiting in line to get pizza with both my kids a lady stepped in front of us. Very very rude people shopping. But great staff! Lines suck but thats a given when you go on a Saturday. read more

Even more rude ghetto types than before. Come in the morning or late at night to avoid them and their offspring.

I went to Antioch Costco this morning, the guy out front directing people was very helpful, his name was Jose, I only needed pharmacy, when I asked another person if there was a line for pharmacy, I was told I would have to go to end of the regular line, Jose told me that if I only was going to pharmacy I would not have to wait, he asked the girl at the door to get me an escort, a young girl named Haley came and took me to the pharmacy, she was very nice. I'm glad that these people work at my Costco, it makes this very unpleasant time a little easier. read more

We always make our large bulk purchases here. The store is usually well stocked with the items they carry. There is not much help on the sales floor but that's how their business is run. Their prices, for the most part, are great! Today, the main reasons for my trip there were Mexican Coka Cola, just like I remember from my childhood and a Prime Rib for Easter dinner. I got both there. Of the stores we looked for the Prime Rib, (3 stores), Costco was the only one with it. The check out is always fast and efficient, although there are always lines. read more

Excellent service Delores at the front return desk was great. Took care of us regarding a discount on several items. Seems to be the overall team focus read more

There are two things that I love about Costco. The gas and the food court. Enough said!

This is probably more of a review of my fellow Costco shopper but......the worst hour s of my life are those I spend in this store. Just going there makes me nervous and I dread the entire procedure. I mean, when, exactly, did shopping become family outting? I swear. The jointnopens at 10am and all the little piggies are lined up outside, clawing their hooves on the ground and anxiously awaiting the rolling up of the door. Mom,dad, grannie, auntie, granddad( in his motorized wheelchair, with his uncovered amputated leg propped up for the world to enjoy), great grqndma, and every child known to man...all unleashed and oinking their way inside, carts going all over the place, unmindful of people.nearby. Why paramedics aren't parked just outside the door is a mystery. Ahhh, I guess this is the rant of a curmudgeon, but I HATE THIS STORE. There, I feel better. Thank you read more

Smaller Costco, but has almost everything. Clean, nice set up - good flow. Parking was easy at 10:45am. Friendly staff. Can imagine it would be harder at weekends as small lot. First time shopping at this one - there may be more parking that I didn't notice. read more

It's Costco, all that is right about American waste... Unfortunately I love it here, another store I could peruse for hours and hours and never get bored... Darn you Costco and your cheaper gas! read more

This is my toys r us, I love this place. No complaints really other then I really hate when people clog the isles to get food samples.

A long past due THANK YOU to Victor (and colleague whose name I have forgotten) for fixing the nail in my tire! I was in and out with exceptional customer service. They even filled all my tires just to be helpful. Good prices great service! read more

The only thing I don't like is that people smoke on the one side of the building and it always stinks having to go through it. Once inside though, the staff is all really nice and knows my family because we are frequent shoppers. I wish they had more of the organic stuff the Concord store carries, but overall not a bad selection. read more

Can never go wrong hitting up the food court for a $1.50 hot dog and drink combo, also $1.50 for a good size yogurt ice cream...shopping for food can make you hungry ;) read more

I hate to say it but East County needs a bigger Costco. I call this the "sample Costco." It has just a fraction of what the Livermore,Tracy, and Concord locations have. For goodness sake I can't even get a roasted chicken here. If I want a real Costco with a variety of things that actually change I have to drive some distance. There is no gas station either. This is a sample store....sorry Costco. read more

I like our costco they have the stuff that is on sale you don't go to empty shelves the employees keep the lines moving so that is great I wish they hadn't taken out the self checkout it is really a pain when you only have one or two items and you get stuck in a line we went in to buy a birthday cake and of course it was a Sunday so the lines were long they kept them moving but it would have been nice a self checkout or even a express lane.The kids really like the food court the berry sundae is a big hit with my husband and kids the pizza is pretty good to read more

I personally like this Costco better than the Concord Location. great service and the employees always treat me well. Gotta love the food court, best way to get some inexpensive grub. Self check out lanes are the ultimate plus for me. read more

We have been to all Bay Area and East Bay area Costcos and Antioch Optical Department was the BEST. Miranda was the took time to listen to my husband's needs. Her patience and great customer service will ensure that we continue to go back to Antioch Optical. Jeremy, her boss was also great. It's not easy finding employees who go above and beyond and listen to your needs. We commend Miranda for her professionalism and awesome customer service. Thanks again. read more

In July I purchased four tires for my car. They decided they couldn't put them on and the reason why isn't important. What is important is the fact that I paid a total of $700 and change and when the refund showed up on my debit card it was for $500. It has now been over three months and more than eight hours on the telephone trying to get the other $200 and change that is owed me. They ought to be ashamed of themselves as I was burned out of house and home in the north complex fire up at Berry Creek and have been living out of my car since then. Right now... I could use every dime. After each conversation, I was told that the remainder of the refund would be on my card within a couple of days. This of course has never happened. The real shameful part of this whole episode is that Costco makes it very easy to contact an actual live person if you have questions about purchasing a product. But if you are inquiring about a refund... It is almost impossible to speak to a human being. Rather everything is menu generated when you call In, With no option for speaking to somebody. So it has now been almost 4 months and they are still holding onto my $200 even though each time I've called they have admitted they made a mistake and I would get the refund within a couple of days. All of the people who have helped me on the telephone have been very nice, when I could finally reach someone. It's the company that is letting both them and myself down. I last spoke with someone yesterday and told them that I had lost everything in the fire up north and I need the money desperately. Costco didn't care. I told the representative on the telephone that I would like a call back from someone higher up in the hierarchy so that I could express exactly how I feel and that I wanted to cancel my membership. If this is how Costco treats people I want no part of putting profits into their pockets. I don't know if I will ever receive the refund, but Costco should be ashamed of themselves and I will make it a point to do business with anybody else but them. This is not something that they can blame on COVID-19. Every time I think about the situation it makes me want to take a hot shower to get rid of the stink of Costco. read more

Absolutely LOVE this place...had to give them a 3 star due to the terrible tire experience i had with them...terrible tires....wrong size and rude employees...the tire shop over all manager was very nice and i got all of my money back....but i have NEVER in my life been treated with such a lack of respect repeatedly in my life.... well i would not buy tires from here..but the rest of the place ROCKS!!!! The pharmacy staff is fabulous...they help you so much and really care about you...... read more

I love Costco. However I wish they would start carrying the harmless harvest brand coconut water even if it is in limited quantities so that I don't have to go all the way to Pleasanton just to get one item thanks if you're listening. read more

My friend drove my car for a while, and found out my tires were not correctly balanced. I only had new tires from Costco two months ago. Since I'm in Antioch with my friend, I decided to bring my car to the nearest Costco. We dropped off the car and walked to a nearest restaurant to eat and kill time. They said about 1-2 hours. Actually only a little more than an hour, I got the call. The guy said it was a quarter off, he fixed it. read more

Wow this costco is huge i love it! The bad thing is they have only few samples counter. They have a tire center and gasoline. Mum said this is big and wont be lost. There are two handicapped lines. The service is fast friendly and accomanding. if you see my youtube video on youtube.com/celestinedailylife just search for east bay costco read more

Not bad crowds for a Sat. Store pretty clean and got our 100 rolls of toilet paper.

Go and they tell me I need a card to go in. Never have I ever needed my card for Sam's clubs or Costco. This Costco is losing a lot of bussiness because of this I'm sure and the rating is definitely lower than any other Costco. Definitely not going here ever again! read more

Victor and Jorge in the Tire Center are THE BEST!! Twice now they've helped me in last minute fixes. They have gone above and beyond necessary to fix/replace my tires. Thank you guys so much!! I cant express how I appreciate it!! read more

Costco shopping is always an adventure!! Free samples, isles and isles of items, and food at the end. We love that Costco returns are always accepted (even if you dont have receipt). We like that we get the coupon book ahead of time to plan out what we will nee on upcoming trips. We always get the pizza or hot dog combo along with a churro. read more

No comprehensive review needed. My comments regarding Costco can be applied to all the different Costco locations. My only complaint comes from when there are lines or 10+ people with filled carts and Costco elects to keep available register closed. That only makes the customer suffer and not want to go to Costco when it is more convenient to go elsewhere. read more

Horrible I slipped and fell last week and they still haven't checked up on me To see if I'm okay. Horrible! How they treat there members

I really enjoy these employees. Employees at the Customer Service and Returns Counter are engaging and friendly. I never get hassled when I need to return an item so I always buy with confidence. I find they have very high quality products and I'm rarely disappointed. The store is clean, well organized and has a layout that flows in a sensible way. Love those samples too. Just bought tires and Costco was the best deal around. Just wish I didn't end up spending $200 anytime I only needed a few staples. I do agree with others that the cashiers who ring you up need to stop all the personal conversations with each other and focus on the customer. read more

What can I say about Costco, I've been a member for almost twenty years and even worked for them for a few years while in college. Great company, the products are priced well and this location is always clean and cool on those warm summer days. read more

I know everything I'd going up but at least costco gas helps save you some money on gas and surprisingly enough it burs just as good as chevron. read more

Nice place, we will be back soon. Good sea food Buy bulk buy bulk. Pizza is pretty good. Everything from vitamins to sodas to wine.

Costco is worth the price of admission. Best quality meat. Prices for the volume of product is unbeatable against any grocery store, although I can find whole chickens cheaper. My Husband loves the food samples but honestly those carts are really just in the way. Maybe there can be a row specifically for those food sample carts? Another suggestion would be to have a check out stand for 10 items or less? Anyway, love Costco! read more

I don't get to come here as often as I would like, but when I do go everyone is very friendly. The food court, while obviously not gourmet, is pretty good. Everything always seems to be tidy and in its place. I love to come here, but always seem to buy a lot more than I went in for. read more

Lines might appear long but go fairly quick with friendly service. Luv the snack bar/gas prices !

This Costco is great! We go to Costco about once a week and every time we go to this Costco we always have a great experience! The employees are all wonderful. They're all willing to help and are very friendly. Wellington is always smiling at the Membership desk. We've used the photo desk for Passport photos. I think they were only about $5 - very reasonable for Passport photos. I appreciate that this Costco is always well stocked. For some reason the Antioch Costco seems to get a lot of items that other Costco locations don't get? I'm not sure if other people have found this to be true but we are always picking up items for family members that live in other areas. The food court is great too! read more
