Find someone that has an american credit card. Make sure they are trustworthy, send them a gift card, and have them give you the CD key.Pretty much the only way to do it. Note that if they catch you doing it, they disable your account and delete all your purchases.
Ah, what a hassle! I don't know any Americans unfortunately, so I suppose Amazon isn't getting my money either!You could always give us the money.
Thanks for the advice guys.
