I have an Apple account and have been using Canadian iTunes cards to purchase music in Canada where I attend school. How do I purchase music from iTunes when I travel home to the US? I believe that I must purchase US iTunes cards to do so, but how does that work with my Apple account. Do I open another Apple account for US purchases, or does my single account keep track of purchases using US vs. Canadian iTunes cards. Using a credit card is not an option for me. Thanks for your help.
If you're going back to the US permanently, the easiest thing would be for you to open another iTunes Store account in the US iTunes Store using your US-purchased prepaid cards (Canadian iTunes cards will not work in the US and vice-versa). It's possible to convert an existing account from one country to another, but not if there's any balance remaining in the account, even a few cents. You'd have to ask the iTunes Store customer service group to clear any remaining balance before you could convert the account. Easier just to do a new account in the US Store.
