Interesting read. . I shop at both Costco and Sams and I can tell you first hand, that I perfer Costco over Sams. Better, friendlier people, better service, less time spent waiting to checkout, and MUCH MUCH MUCH MUCH MUCH better warranty. Costco will let you refund anything (except PCs) if you're unhappy or it breaks. Lifetime warranty on the products they sell.
