Any self-respecting geek knows that ThinkGeek is the place to go to pick up some hardcore geek t-shirts but there’s never been a better time than now thanks to their latest promotional deal.

Between now and midnight Sunday January 18th (EST) you can get any three of their geek tees for the price of two. To take advantage of this promotional offer simply follow this link, pick out three of your favorites from the many cool geek t-shirts on offer and enter the discount coupon code ‘FREETEE’ at the checkout.

I’ve picked out some of my favorite ThinkGeek tees above but if none of them appeal to you have a browse through their entire geek t-shirt collection here.
