Here is the best interview I've read with the guys. It pretty much covers everything. Matt and Mike Chapman run it, and they were able to quit their jobs because the merchandise was selling so well. All the history is in the interview too, as well as what
frenchblue said.
And
this site has all the info on the emails. There was another site,
www.the-coolest-stuff-ever.com that had a ton of great info too, but when I got back from my honeymoon at the end of May, it was just gone.
