Ok, I have an iTunes account that is linked to a credit card that I use. It's one of those credit cards that you load money into everytime you need to. Right now, I don't have any money on the card, but I want to buy the AIM app. Is it possible that I can use my mom's credit this one time to buy AIM and use the other credit card every other time? I tried buying AIM with my credit card, it told me there was an error (no money) but gave me no other options for a different credit card. So, can I use a different credit card with my iTunes account this one time? I know that I can probably just create a different iTunes account with my mom's credit card to buy the AIM app, but then I wouldn't be notified with updates unless I signed onto it, which I wouldn't do. I know this is pretty confusing, but I think you can understand..
