woot
I really love woot.com. Not so much for their hardware, which I think I've purchased once, but for their insane shirts. I got one for Susan last week that featured a fat unicorn eating a rainbow, and she loved it. Today they have a shirt up that led to me clicking the buy now button the quickest I ever have. In big capital letters it just says I AM THE INTERNET. I feel this way a lot of the time, and now I have a shirt to express it! Yes I know I'm a gigantic nerd.
