T-Shirts Site: Threadless.com

Threadless is one of the better sites for well-designed or high concept T-shirts. The shirts there are very colorful which is great, and they are relatively cheap ($10 for a t-shirt is pretty cheap). The artists are from all over (appearantly the dude who's shirt I bought is from Netherlands, which some how makes me like the shirt less).

What makes Threadless such a clever idea is that the designs are submitted by users then judged by them. The designs that are score high enough are sold through the site's store, and then the user that submitted then gets a cash prize.
