I like Costco too, however, BJ's is better if for no other reason then they allow you to use outside coupons and they have a wider selection of Brand Name items, not just one. Example: Peanut Butter! At Costco's you will only find one brand, whereas at BJ's you can chose between Peter Pan and Skippy. Not much difference in quality, but, some, like me, like to be able to go with the one I like best.
