I've used it at Wal-Mart several times as well as many other places that don't take Google Pay or Apple Pay (i.e. Chick-fil-A, CVS, ****'s Sporting Goods, etc). The important thing to remember is that just about any place that allows you to swipe your card will work with Samsung Pay. After unlocking Samsung Pay, just hold your phone near the magnetic swipe and it will work. Most retailers tell me that they don't take payments via phone and then are surprised when it works. It's actually kind of fun...
