Ok well I'm trying to buy microsoft points to download Halo, Fable, and a Halo 3 map pack but it everytime I enter the debit card it keeps saying that it can't be authourized. It's my grandmother's so we don't share the same last name and she has the card set for her summer home, not my home. Could those be the reason? And if so how could I get points without buying a prepaid card? I don't really want to beacuse then I'd have to spend $48 and I on;y want to spend $35. As you can tell I just got my xbox too =p
