credit card help with itunes? So in order to have a membership for itunes I have to have a credit card, but I don't, I'm only 13. My mom won't let me have her number, because I'll run the bill up, supposedly. So they sell like credit cards you can get where you pay like thirteen dollars to get one, and then put on money as you go along, I think. Would this work and help me get an itunes membership? I tried Lime Wire, but then I found out it's illegal and you can get lots of viruses, so what do I do? I already have songs from my cd's on my ipod shuffle, but I want itunes. Help!
