First you have to get an account at rewards1. Just click on this link to go to the Rewards1 website and make an account. I recommend making a new spam email such as yahoo or gmail to use just for offers and to keep the nasty spam away from your real email. Make sure that you use all your REAL info when you make your account so they can send you your prize.

Next you click on available offers. I suggest doing free offers so you don't pay anything but alot of people do the cellphone offers too. Most offer only take a couple of minutes to complete if you have a fake email and address. You can use the address of a Walmart or something if you need a address to use. Then you just complete some offers and you will get your Gears of War 2. Remember that 1 point equals 1 dollar. So you can have whatever you're aiming for (MS/Wii points, consoles, free Xbox Live, etc.) in a week or so depending on how diligent you are on completing offers.
