Well, they do say nothing is free and that is the case here as you have to buy something worth $20 or more from ThinkGeek to actually get this free tee. Having said that if you have ever visited the ThinkGeek store this might be just the excuse you have been waiting for. And if you haven’t visited the ThinkGeek store what are you waiting for?
Stock are limited though so hurry! Oh, and it’s in celebration of their 12th anniversary.
