Learned a little trick, this is what you do.
Use that for whatever credit card you want to "refund"
!!!PRINT WITH SOME THINNER PAPER ABOUT 1/8"!!!
Tell the cashier (Gas stations and Gamestops are the best) that you made a electronic purchase of a gift card and it doesnt work
They will think it is real if you are smart with the fake receipt that you print out.
They will give you a real one ;)
Thats about it, enjoy! :D
