As many of you may know, you can queue up demos and other content on your Xbox using Xbox.com. However, it was recently discovered that there is a small glitch in the service. If you try to add a demo to your queue but are not logged into the site just yet, you might accidentally purchase the item instead. After you click the “Try Game” button and log in, Xbox.com acts like you tried to buy, giving you a “Confirm Purchase” button. So be sure to read every button from now on so you don’t accidentally buy one of those overpriced “Games on Demand.”
However, this may not be an issue in a few weeks, as Microsoft has promised that their web team is working to fix the problem.
