|Over at Slickdeals.net I noticed that Gamestop has a $20 Rebate Form good on any Activision game (or combination of games). The rebate link above lists all the games eligible, but here are a few that caught my eye:
"- GUITAR HERO III: LEGENDS OF ROCK (SOFTWARE)
- TONY HAWK SERIES
- CALL OF DUTY SERIES"
So check it out. Be aware that Guitar Hero 3 is the software only and not the bundled pack with the Guitar. This is a good deal especially if you can get 2 games for less then $50 after the rebate... that is if you have any money left after buying SSBB.
