We had a minor glitch with something we bought and took it back to Costco. They heard us out and asked us to contact the company directly. After understanding our problem properly, we were compensated with a full refund. The customer service rep offered to bring the manager to hear us out and the manager, Michael, did exactly that and issued us a refund...leaving us as happy customers and Costco fans!
We go to costco specially for some things:
big box of blueberries
eggs-24 for 1.89 I think..
strawberries
hummus
tide
papertowels
kirkland's green dish detergent-that smells great and lasts forever.
sometimes they have yummy deseeded pomegranate at the cheapest price I have seen.
I have however noticed that red onions and lemons sold in bags at costco are not always fresh.
They also have free samples of some of their products on saturday, but I avoid that time as parking and the check out lines are a nightmare.
And if you sign up for the american express costco credit card, you get cash back annually that can be redeemed for cash or cotsco dollars at the costco store.
