Shirt.Woot! makes some cool tees and they sell them at a reasonable price. Just $12 on the first day and $15 after that until they are discontinued. Of course, we can choose the t-shirt usually. We can see what we are going to get before we order and that’s always nice. Even the pretty crappy mockups that they provide are better than nothing.
But as evil as it may sound to some people $6.66 is a pretty cheap tee.
