Plan to get 3rd serve (family member), and was wondering if Walmart will accept credit card to load $500 to temp card, or should i just get a VGC to feed new baby? However, I am torn between 3 serve / 1 rb, or 2 serve / 2 rb... what about you?

note - i got first 2 serve cards at CVS so paid with cold hard cash bec i didnt see serve in my WM few months ago.
