I dont know if this will work with a $3,000 card, but worked wiht $100's
Go into best buy and buy something $3100.00 and pay the $100 difference with a DEBIT card. Drive to the next closest bestbuy and tell them you bought it for a wedding gift for your brother, but your wifes brother just called you and said he bought the same thing and you need to return it.
when the return the item, ask to have the balance put back on your debit card. if not, then your back where you started from minus a few gallons of gas
around xmas time, i would get bestbuy and circuit city gift cards from relatives. instead i wanted thc cash and used to do this and it worked almost every time
