I have had a Sam's club membership for about 10 years. The meat is awesome, great price on poultry and sometimes seafood. My wife buys a lot of items like laundry supplies, toilet paper, etc. I have bought tires and car batteries, clothing items, vitamins, and a lot of other stuff that pops up as a good deal. There has never been an issue regarding quality.
Ask what kind of incentive package they have for new members. My son joined last year and got more on the spot in value, gift cards, and freebies than what he paid for the membership. He actually made money by joining. He even got a free lunch there, and went on an in-store scacanger hunt for prizes.
