Hi
Looks like you and I live in the same place well I live in Cape Coral but I never can get my S6 to work at the Walmart Neighborhood Market but the last time I was at the normal Walmart it worked. I am gonna try it asap again. I heard from another poster they said BY THE STORE that S-pay is not allowed or will not work. I think same with Apple pay and Android pay. I MIGHT try that for the heck of it.
I think the shape of the machine at the Walmart Neighborhood Market will not let it work that is my thinking.
