    Great Value and Organic Selection Costco in Eureka is always clean, well-organized, and stocked with great deals. Since I'm not from this area, I really appreciate the wide variety of organic goods that aren't available at my local store. The staff is friendly, efficient, and keeps the lines moving even during busy times. Parking is easy, and the gas station prices can't be beat. A reliable place to stock up, save, and discover new finds.

    Recently, I split the bill with my partner and the cashiers were more than kind to allow us to split the bill. Their restrooms are always clean looking and smelling. My favorite is how the soap smells after you wash your hands. I appreciate how professional their tire staff was. Also, if possible and at your disposal, don't forget to wear a flamingo shirt or clothes on Fridays apparently staff do. Adorable!

    So happy with this delivery order

    I ordered a birthday gift for my sister-in-law this evening and it arrived within an hour. It was a bouquet. The second item was fresh coffee beans. Look at what they delivered within two hours! She lives in McKinleyville and was very happy. Awesome work Eureka Costco!

    It's over an hour for us to drive to Costco , but the friendly folks that greet you all the way to the church out folks are super nice, the store is clean and upbeat, covid rules are being enforced. Recommend

    Okay guys, what is with this Costco management? Like honestly I love Costco and it obviously deserves 5 stars but not from me at this time. I get it's in a bad area of town with drug addicted homeless, but I have never done drugs nor do I look homeless, no need for security. When I went here with a friend the employees seem to have a rude arrogant attitude, and I felt very harassed so we left. Not a way to treat customers, or obtain new ones. The Optometrist and his receptionist are the exception to this Costco, very considerate of their clients. Wish I could say the same about the rest of this Costco.

    I like this small town Costco more than I like the big city Costco's because here in Humboldt County all the employees are friendly and very helpful when you ask for help. It does get really busy (as any Costco does) on weekends but during the weekdays it's a nice shopping experience. Overall I do like to shop here. This is also the cheapest gas in Humboldt County which is the best part of this Costco for me.

    Rudest attendant ever. Honestly, why be in a customer service type job if you are going to treat…read morepeople in a shitty manner. We needed to put a bit of air in our tire since the last gas station had a broken machine (some tweeter took a piece). When we asked the attendant if we could use his, he stated, "you have to pump gas or buy something". We proceeded to buy something since we obviously did not need gas. Once we bought something, he refused to let us use it, said, you only get to use it if you buy gas. Either way, purchase or not, there was no need for the rude attitude and deceitful narrative.

    Zero stars ! Worst experience ever. Pump didn't work. I only bought a small amount of gas. Gas…read moredidn't pump into the car and still charged me. I explained to the Owner who ended up CALLING the POLICE (who were equally offensive and useless) that the pump may be broken or something but it didn't give me gas. I cannot even believe how unhelpful they were. I explained it was all I had in the bank today and just enough to get home. Didn't make a difference. I was completely blown off by the owner who just told me he wouldn't do anything and I must be lying. What a horrible experience. Police? FOR $6? Insanity. I'll never stop here for gas. I'll go to the shell on 101S any day. Today made me lose faith in humanity. But the attendant at shell station / pinnacle 365 was SO KIND and explained he would have been able to tell if it had given me gas or not. So I call bs on this gas station. How jaded can you be that you don't try to resolve a $6 issue and choose to call the cops? I was not being unkind or harassing anyone, all I was doing was very politely asking if anything could be done cus I'm just trying to get home. I have given 10 years of my working career to this community. To not be helped when a basic issue is caused by a broken gas pump when all I needed was to get home and paid the money, was offensive. I always help people in need always without question, as best I can. The sheriff even told me "if you run out of gas the CHP will come give you some" ............. Thanks great use of tax payer dollars instead of resolving the issue with the pump. Never ever again. This place sucks! I bet you it's going to happen to multiple people. I'm supposed to call the person who calibrates it who works with the county. And I will! I don't want this to happen to anyone else it was scary. Zero stars
