I agree with everyone else, max anyone would pay is maybe 50% to 75% of the face value of the card. Shouldn't have refunded through PayPal, paying with card gets you a refund through card.
I'd take @Berserk deal as it's really about the best you're going to get. Why would anyone trade $ that can be spent anywhere, for something that can only be spent in one direction, for the same dollar value?
