I have a walmart and a sams card. If you want the interest promo go for it but theres really no other reason there both GEMB and they both work at either store. I had the walmart card and then one day decided to open a sams membership and they asked me if I wanted to apply so I said sure. It wasnt till he told me I was approved that it worked at walmart too. If I knew they were interchangable I never would have apped I would of just used my walmart.
