Hi all. When using a Gift card with iTunes to rent TV shows, buy music, etc... and NOT a credit card, it can never run out, either that, or your gonna be short sided by how much content you can get for the price remaining.. How does Apple deal with this ? As one would think no expiry would mean theres always gonna be some credit left... a few cents to $1 .... I know you just buy more Gift cards, but you have another card, more credit = no the same one. What can you do in this situation to make sure all credit is used....every last cent. as If i buy a $25 gift card, I wanna use $25 up.
