Threw what methods are the cards bought?  Do you have proof with like receipts that it was paid for with cash or anything?

I am kinda leary of Itunes as so many turn out to be carded at low price.  Apple sent me a really nasty email with a 50 dollar one I bought once that was a good deal turned out was carded... after that I have always made sure it's not been bought by credit cards as high chance of carding.
