I just discovered WOOT. It’s the perfect impuls buy site!
They have a daily special, and usually a good deal that you can buy untill it sells out.
Every day at midnight WOOT posts a new deal, and there’s quite a community out there they wait patiently for midnight (central time) to roll around what else they can spend there money on again.
Some things you might find: Computers and accesories, Pulsar Watches, Roomba vacuums, DVD recorders.
You can actually find a feed further down the page of the current special.
W00T stands for We Own the Other Team!
So be prepared to be w00ted and pwned! There are some good deals to be had!
