“I'm sure it's been said before, but this is not the regular Costco. This place carries different items or the same items in different packaging. No clothes, no gas, no food court. Just serious business shopping.
Set up more for retail shops and offices, you'll find truly bulk items in everything. Meats, cheese, Sodas, seafood, vegetables... large packages. That doesn't mean you can't use it at home. Just keep on mind that some items don't come in boxes of cans, it may be in 120oz cans such at tomato sauce or olives. Or you may find 30 lbs of shrimp.
Keep an eye on the coupons in your mailer. They will sometimes list fantastic deals on somethings. 65 taquitos for $9!! Feeds a party easily.”

“At the Cypress location all the pharmacy people are amazing. From all the pharmacists to each of the cashiers. All are so patient and accommodating. I've been a member over 10 years and would never consider another Pharmacy, even if it was another Costco.”

“This Costco Wholesale is located near Tustin Blimp Hangar #2, and it’s one of my top three Costco locations in Orange County over the past six months.
It’s not too crowded on weekday afternoons, parking is plentiful and easy, and the store itself feels spacious and clean.
I also tried their mint vanilla ice cream for $1.99, and it was actually pretty good.”
“Vulkan Fight Company completely exceeded my expectations. I reached out with a question about my order and they replied immediately with clear, helpful communication. They double-checked shipping options, confirmed sizing, and made sure everything was set up to arrive as quickly as possible.
What impressed me most is how attentive and professional they were - especially after dealing with another company that completely ghosted me and never shipped my order. Vulkan was the total opposite: responsive, reliable, and genuinely customer-focused.
Highly recommend Vulkan!”
“never knew this place existed until i saw it on social media. these are amazing discounts on a variety of things from summer to winter items to home appliances to furniture. the safest purchases would probably be the clothing. but be careful on everything else because most of these things are probably returned items. and the packaging does not tell you why it's there. it doesn't say if it is defective, overstock, or damaged, missing parts etc. shop carefully!”
“Love the quality of food & service. The deals are great & the bonus I bag as I go & no need to stand on a line yo check out. One day I forgot my purse & it did not matter......have palm of my hand shall shop!!”
“I been going here for a long time and always been given professional service and quality work on my vehicle. I will remain a customer here and they also have reasonable prices on all of their items. See y'all again for my next future service, thanks to the owner and all the staff and employees there”
“I love Costco.The store us clean , employees nice.Only problem I had was they didn't have their Kirkland Diet Green tea .Hope they bring it back.
Went today and was told they only have tamales round the holidays.I guess a new policy because I have always bought them whenever I go there. Very disappointed. 2/19/2026”
“My job has been working with this company for the past 10+ years and honestly they are some of the most genuine and kind professionals I’ve ever worked with. Great communication and customer service and lasts willing to help with our custom ideas and crazy deadlines.”
“Overall I really like Costco, but this particular Costco is usually very busy and feels chaotic inside. You often need to park far away from the entrance and the gas station line weaves through park of the parking lot.
Edit: They fixed the gas station issue, so I am now giving the Costco 5 stars.”

“This review is for the house special crab, you order and pick your crab at the seafood spot, tell the worker you want to have them cook the crab, minimum of 3lbs, and then you go to the food to go spot and pay and let them know what flavor you want. You can have house special or salt and pepper. Definitely get the house special flavor. It's really good. You add addition $3 a lb to have them cook your crab or lobster. It's a lot cheaper than buying it at a Chinese restaurant. Would definitely order house special crab at ABC again.”

The belt is absolutely beautiful, and the quality is amazing. worth every penny. Thank you to everyone at BB Simon who helped me and made my belt!”
