American Express and iTunes!
Did a quick search on this forum and noticed there weren't any posts regarding this topic. I found out the other day that if you register your card (if you're already a member) American Express will reimburse you for up to 5 song downloads.
The main stipulation is that you use your AMEX card (duh). This offer is available directly on the front of the American Express site (since I just signed up can't post the URL). If anyone else would like to post the URL directly to the iTunes enrollment page, it would be appreciated.
I thought this was pretty cool, so passing it along.
