I don't usually play the Walmart VGC game, but needed to do so this quarter for Freedom. Went to a store which apparently does not sell GD VGC on credit (apparently this is a store level decision), but I smiled at the cashier and inserted the card. Her supervisor made me take it out, but then said "it says Chase on it so it's debit." The cashier was perplexed why the screen still said credit, but the transaction was approved and no signature was required for a $500 card (which would have probably been a tip off).
