Found a great points site called
www.freexboxlive.com it is great because the offers are very simple and cash almost instantly. They also offer a wide range of prizes mostly for gaming like xbox, wii ps3 etc but they also do gaming time like WoW time and Runescape Time. You can also custom order from 6 different (preferred) sites, amazon, ebay, newegg and more.
