Threadless!

Threadless is basically a website where you can buy tshirts. Their point of difference is that all the tshirt designs are uploaded by the public. Yes, anyone can potentially be a Threadless designer! The huge and eclectic pool of artists means that you can find a massive range of graphic and illustrative styles to choose from – there’s funny, there’s cute, there’s simple, there’s ridiculously detailed, there’s sweet, there’s sarcastic, and everything in between.
My own experience with Threadless has been very positive. I ordered a couple of tshirts for my niece and nephew for Christmas last year. Here's Ryan wearing his (check out his oversized noggin' complete with bruise!):

And recently I bought a couple for myself, and one for the husband (you can see us above). Here's a few others i wouldn't mind owning either: 1, 2, 3.
Their customer service is great, the shipping is very easonable, they have regular sales, and the shirts they use are sweatshop-free. Tick, tick, tick and tick.
Oh and p.s. Threadless now sell art prints of some of their designs too. I wouldn’t mind having this up on my wall:
