Wholesale Stores near Pittsburg, CA

“This Costco is just like the others you've seen, except its food court is laid out differently. As for the store, it has all the usual stuff with the regional extras that make it the Costco for the area. A little customized to make shopping a better experience. What about the new baged chicken? Saves a lot of plastic and minimizes the waste.”

“Good gas prices always.
Busiest Costco in northern CA according to the manager. This place can get super crowded.

Take advantage of the 9am early hours or shop late around 7 to avoid most of the crowds.”

“It's Costco. You pretty much know what to expect. The parking lot was large, but probably gets full at peak times. Great view of Mt. Diablo walking out the front door”

“I have been a Costco Member for many decades. Today was the first day I patronized the Pharmacy at the Antioch, CA Costco. I received great service from Alex (via a Phone call). As a first time caller, I had no clue how the Pharmacy service works. Alex, patiently and professionally provided answers to my many questions. He also spent the time to listen to their voice mails in search of the message my doctor left with my new Prescription. I originally told him that my doctor said he spoke to one of the Pharmacy staff which was not the case. Because of the high quality service he provided me today, he definitely should be recognized by upper Costco Management. I could not find a way on the Costco web site or system to leave a review or feedback; therefore, I am using Yelp. Hope this helps my fellow Costco Members. Thank you Alex, Ed Woo”

“Tonight's visit to Costco in Antioch was a pleasant experience, particularly with the seamless transition of holiday items in and out, showcasing their consistent attention to seasonal offerings throughout the store. With spring in full swing, I noticed an expanded selection of plants, including several varieties I hadn't typically seen at Costco such as various dwarf fruits, all available in ample quantities. This focus on seasonal diversity enhances the overall value of the shopping experience, making it effortless to discover something fresh during every visit.”

“Went to this Costco for a return... the line was insane.... I don't know if it's because I came on a Friday around 2:00pm... but the line took forever... BUT- the reason for this review is not because I love writing reviews. Its more to recognize the service I received... It's not often that I go to costco and I have extremely helpful people... this Costco however, has always been great. With the line being long, being tired, being annoyed that the line is too long... (lol) when it was finally my turn I was greeted with a big (happy to work here) smile... which you know what they say is contagious... Prado, I think that was his name, he was so helpful, so informative, and it didn't matter if there was a line behind us, he made sure to help me understand any future return questions I had. He seemed sincere and genuine about our quick convo about the Korean BBQ and that's what customers need after waiting in a long line... (yes still talking about that line) So shoutout to Prado (sorry if i got this name wrong) Cheers!”
