The idea of TeX.SX T-shirts came recently up in the chat. Would there be any interest from people to buy one? The idea is that we designed it ourselves and have it produces.
I just had a quick look and found an online shop which allows people to upload and sell their own T-shirts (and pullovers, etc.). When the commission you could get is set to 0 a basic printed T-shirt is around 18-20 Euro inkl. shipping (varies from country, shipped from Germany; this was based on a relative simple shirt ca. 14 Euro + 4 Euro shipping around Germany). This is nice because others websites make you buy dozens at once and then one of us would have to ship it to everyone else. This makes it also relative risk-free because we don't have any minimum number to order and uploading it is free.
The question of copyright came also up. Could the official stackexchange staff, which also reads this meta, please give us an idea if using the {TeX}
logo and the tex.stackexchange.com
URL would be any issue. I personally guess not. It's basically free advertising for them as well. We can of course use some other place as well if we find a better one (shipping to USA is for example already at 9 dollar).
Paulo Cereda already made an example T-shirt, so I include it as an eye catcher:
I would be happy about any feedback.
