Hi there, I'm a teacher and I want to give a couple of students "prizes" of mp3 downloads for good work in class. I'd rather do this than give candy, etc. Unfortunately both iTunes and Amazon Student require credit cards (or checking accounts) to open accounts to even redeem gift cards! Where else can I simply buy an mp3 gift so the student can just "claim" it and download without needing to provide credit cards or checking accounts? Thanks!
