Support charity and look good doing it
Best Buy is putting on a charitable endeavor to attract gamers into helping the Boys and Girls Club of America (bless their hearts). For only a buck, you will be providing a solution for teaching children how to use computers and be more creative. Your reward will be instant gratification for the support and a neat Xbox 360 wristband similar to the Livestrong campaign. Remember, "Life is your Game," so do it for the kids!
Heck, who wouldn't want a flashy green wristband like this anyway?
