I got the $10 code in an email that said
"Thank you for purchasing "Forza Motorsport 4" from Amazon.com.

It sounded like a general gift card-type (since it specifically says it excludes MP3s) so I entered it there, but when I checked my balance it actually gave me $10 for games, $10 for mp3s and $10 for video
I haven't bought anything because I don't want it revoked and charged but it says so when I go to check my promo balances on amazon MP3 so I may try and buy some stuff
Can anyone else confirm?
