i was wondering is it possible to send iTunes Gifts through store credits without a credit card? Thanks!
I think you can't do that. I tried to gift my friend a game through a store credit, but in fact I need a credit card to give a gift to my friend
No, unfortunately not. http://support.apple.com/en-us/HT201783 "When you purchase an iTunes Gift, you must have a valid credit card on file; you can't purchase an iTunes Gift with store credit."
