I understand the obvious that they won't let me buy something with a credit card and then return it for cash or check, but why if I bought in one Visa and then coming to return, they demand the same visa card? Why would it matter to them if I gave them a different Visa card? or even Amex/Discover, they could make money with higher fees refund from the cc companies...
What if I canceled the card in between the time of purchase and the time of return?
