My name is Bryan and I want to GIVE you free Xbox Live marketplace points! Seriously! Check my first blog entry if you are wondering how I can give away all of this free xbox live stuff. I love free stuff and I'm sure if you are here then you do too! If you have any questions just go to the forums or the proof pages.
Why? Because I have tons of them and my friend wants me to promote his site!
All that you need to do is register on this site and I will send you the entry form for the contest. There will be one drawing per month. The number of codes given out will be determined by the number of new entries per month. For more information check out the Rules section.
