Store card can only be used at the store, Discover version can be used anywhere that accepts discover
Edit: You can use it at sam's club too, and walmart gas stations
So, lets say I get the store card, how often would I have to use it before it turns into a Walmart Discover card you think? I mainly want it for the free monthly TU score, but it would be an added bonus if it converted into a Discover. Problem is, I dont shop often at Walmart.
