Can I give something using my iTunes gift card? I want to give an itunes movie to a friend but can I use the credit I have on my iTunes gift card?
You should be able to click the present option or give to a friend or whatever it is called.
You pay, so it works without any problem.

Why would you think using a prepaid card like that does not work? It's a great method used  worldwide by people who don't have a credit card, or do not want to  link them.
