I just got some itunes gift cards and now I'm ready to use them for my mac. I've never used itunes gift cards before, though. When i tried redeeming the code on the Mac App Store, it asked for my apple ID, so I typed it in and it said: "This Apple ID has not yet been used with the iTunes Store. Please Review your account information." I clicked "Review" and when I got to the credit card number part, I decided not to type it in, because I don't own a credit card. Therefore, it did not let me redeem the code. Is there any way I can redeem some money and buy some apps without giving out any credit card information? Thank you, please reply quickly. P.S.: please dont reply with simply a link. No apple support article has answered my question.
