Not enough money to pay off iTunes App
So today I bought a game app. but I just noticed I didn't have enough money on the debit card. Would like Apple send you a bill to your address? Or can I like pay that 0.99 cent by adding a different credit/debit card or buying a itunes gift card, if so, how do I do it?? Also, would there be extra fees or anything? I know the game is only 0.99 cent and thats really nothing but I would hate having a bill for something that cost this little. I'm using a Vanilla Visa Debit Card by the way.
