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.
Honestly I am not sure what carded means in this case but I can tell you that I have a physical card and a physical receipt from Walgreens that is $15. I thought it would be easiest to just send the card code to you rather than send the card via mail. Thank you for your interest!
