This is not so much a one off deal but an ongoing one. For those who have been into deals for a long time you will have heard of http://woot.com. They also have a t-shirt site which features one artist's design a day. Usually for a very reasonable price. They regularly have competitions to select new designs. Unlike for the main woot site, they have international shipping, and it's set at $5!
Just thought I'd throw this out there for anyone who was looking for some new t-shirts.
