I have been using a US iTunes account since November last year, I have bought quite a lot from the App Store only using iTunes gift vouchers, I haven't used a credit card at all with my iTunes, just gift card codes.
My question here is, if I just keep continuing to purchase things off iTunes using codes instead of an actual credit card will I ever eventually get told by Apple to use a credit card or is it safe to just keep using gift card codes?
