Oh in case you don't know what woot is. Heres the wikipedia article:
http://en.wikipedia.org/wiki/WootWoot-Off
The site will occasionally deviate from the one-product-per-day model for a “Woot-Off”, where a succession of products are available for a period of unannounced length, usually 24-72 hours. This mode is indicated by rotating lights and a bar indicating the usually undisclosed amount of product remaining.
During an average two day Woot-off, Woot's sales typically exceed one million dollars.[4]
Basically during a woot-off you can get crazy deals on all kinds of things. Zune for $50, radar detector for $25. Sometimes they have really good stuff, and other times its crap.
