Another option is to create a "store" on Spreadshirt, 99dogs, or cafépress - google to find them, they'll be on the first page of results - and link there so shirts and other items can be printed on demand.
If I was going to make a recommendation, I'd probably go with Spreadshirt, beause they have a European operation. Dunno about 99dogs, but cafépress doesn't, and the shipping prices are ridiculous (and you can only get white/grey shirts).
