Woot.com may be my favorite online shopping site, with it’s 1 item per day, WootOffs! and Random bag o’ crap. I actually have a friend who has an alarm set to 10pm PST to see the daily Woot before it gets sold out.
WootWatch (available here) does a great job of showing the daily Woot deals, including those for Sellout.Woot, Shirt.Woot and Wine.Woot. Also, if a WootOff has been detected, it will automatically update you when a new item is available (providing you leave the app open.) Best of all, WootWatch is free!
