I have an itunes music card and I dont know what you have to do on itunes to use it.
(if that makes sence) help please
1) go to iTunes store 2) on the far right, under "quick links", there should be a link called "redeem" 3) click on "redeem" 4) fill in the code you see on the card, then click redeem 5) if there's a next page, just click accept XD
Hope this helps =)
