Are you one of those Xbox LIVE Rewards users? If you aren’t you should be as Microsoft pretty much uses it to dish out free points for making purchases on Xbox LIVE that you were going to probably already make anyway. If you are, now is the time to pick up your free “Xbox Loves You” avatar t-shirt as a thank you for joining the program last year. If you’re one of the lucky few, the email account you used to sign up for Xbox LIVE, then redeem the code, and spice up up your avatar’s wardrobe.
