Woot.com is a site that sells 1 item per day, but at times they have a "Woot-Off". A Woot-off is when they sell items until they run out, and put a new one up. These usually last for a couple days, but near the end they put up Bags of Crap. There's a limited number, and a BOC can contain anything in the Woot facility. You could get a box full of iPod cases, MP3 players, those prepaid cell phones, or maybe something even better. It can honestly have anything inside. I remember a while back some guy got a 42" flatscreen TV with a crack in the frame that still worked perfectly.
The best thing about the bags is that they are under 10 bucks.
