I have an iPad and its connected to my credit card, I want to purchase gems in a game I'm playing, but I don't want it to take the money off my card, instead id like to buy an iTunes card (I'm not sure if its called iTunes card or if there's a different one for apps) is it possible to purchase gems in an app with the voucher/card or would I have to take my credit card off my iPad?
