I put shirts on two sites:
http://www.zazzle.com/subsonicradio
Has a much greater selection of shirts and you can even customize shirts by adding text or other images to it but is more expensive.
http://www.cafepress.com/subsonicradio
Limited range of shirts but cheaper.
FYI: I don't make any money off the cafepress shirts and would prefer to not make money off the zazzle shirts but the force me to mark them up.
I want SR to be completely free forever so don't think I'm in it for the money. It's not "helping me out" buying shirts. I just want people to represent what they like. 
Don't forget, the main thread is here! Please continue discussions here and let us know which color shirts you get!
