When I lived in Potsdam, we often had to get t-shirts and sweatshirts made for various Clarkson University events and happenings. We always used Great Northern Printing since they were the only real printing store in town- sometimes with mixed results. One time they printed a whole run of 50 t-shirts crooked and tried to tell me that they weren't and that I was imagining things. Another time they misspelled my text which was obvious. Yet another time they reversed the colors of my graphic. Hit or miss, but if you want t-shirts fast this is your only option in town.
