I read somewhere on these forums (can't remember exactly where) that you can get refunds for items purchased on iTunes. It's not even that hard to do. A few clicks. I got a bit trigger-happy over Christmas and slightly overdid the tv and movie purchases. I'm happy to report that Apple was happy to refund the ones I subsequently regretted (and which I didn't watch). Suddenly I'm all in love with Apple again. And you guys. Obviously.
