I just received in the mail, a t-shirt from changetheworldtshirts.com along with a bunch of bumperstickers!
It's pretty sweet:
I'm also really excited about this business model. They are really serious about value added. Part of the profits from every shirt sold goes to one out of a list of charities, which the t-shirt's new owner chooses.
I'll be wearing mine in an upcoming video for sure.
