Free Guitar Hero: Metallica export code (PS3 and 360)

I know it's a bit early to post it, however the deal actually starts on the 28th/29th of September for us.

"Bring your Guitar Hero: Metallica songs into Guitar Hero: Warriors of Rock to experience them in a whole new way! Play with any combination of instruments, compete in all-new gameplay challenges and use enhanced gameplay powers to shoot up the leaderboards! For one week only, get the disc import code here for FREE!"

Worth about $6 I think, not sure though - good deal for Guitar Hero fans like me, however the unique code on the back of the Metallica manual is required to actually redeem the song export.
