Just a quick heads up. Walmart has two new variable load cards that I was able to purchase with a Credit card last night.
THe first one is silver and says "FATHERS DAY" on the front. It can be loaded with up to $500.
The other type of card is a NEW variant of vanilla that I have never seen before. It is a "One Vanilla Mastercard"

Fathers Day card is issued by Sunrise Bank.
This could be lucrative for the right people. Some WM-NM will code as grocery for 5% CB. Also, when CC are allowed for a purchase, that often means WM GC are allowed too (I have not tested this).
