I have gotten a few really cute t-shirts from shirt.woot.com over the past couple of years. Shirt.woot is a site where people submit different t-shirt designs that they have created based on the current theme provided them, and then the users of the site vote. The top three designs are then created. The shirt is sold for $10 on the day it is first introduced, but if it remains popular you can continue to buy it for $15. While only one shirt is featured for sale on the main page everyday, the other shirts still available can be found through the reckoning tab. As shirts fall in popularity, they are no longer available for sale.
Here are some currently available shirts:
The Epic Begins – $15.00
Nature Channel – $15.00
Imposter – $15.00
