Earlier today, the Xbox.com team added the ability to preview and purchase Avatar Marketplace items and add Games on Demand to yourXbox 360 download queue. Swing over to the Marketplace on the Web and browse the new addition if you are looking for something to wear or play today.
Update: The Avatar Marketplace on Xbox.com has been temporarily turned off for maintenance. We expect to have the feature returned to use in the next few days. While our teams are working on the site, you can continue to use all the other features of the Web Marketplace. This does not affect the Avatar Marketplace in the Xbox 360 console.
