Ok, I don't usually do this kind of thing, but a buddy got me to check out gaminglagoon.com, said he already had gotten a free Microsoft 1600 Point card for his XBOX 360.
So I tried it out, during the Daytona 500 I managed to get 15 points. Last Monday during lunch I ran up another 5 points and got a Free Microsoft 1600 Point Card two days later shipped directly to my house from Amazon.
Just fooling around at lunch and during yesterday's NASCAR race I ran up another 40 points. Two more cards headed my way. Pretty easy stuff. They also have prizes for Wii, World of Warcraft and some other stuff. You can also get XBOX Live memberships and accessories.
