A strange thing happened to me today when I was purchasing 2 x $1000 MO at my local WM...I was using VGC from GiftCarMall - 3 of them went down as usual as debit (where I had to enter pin #), but the last apparently went through as credit card (no pin was required)...the MOs printed normally as usual, but receipt indicated 4 cards being used - 3 "debit" and 1 "Visa"...I think I was more worried than my cashier - I didn't want their register to be short, but the cashier said "no, it all went through fine, the machine accepted it as credit card", and when I later checked the balance - it was 0...so it definitely went through...did it auto drain itself?...or maybe the cashier hit some button that made it do that?....has anyone had anything similar??
