It is hard to imagine that Think Geek has been selling stuff to smart masses for ten years.  For the last 10 years geeks have been able to purchase cool gadgets, funny t-shirts and just about any form of candy with caffeine infused.  To celebrate, think geek is offering a special limited edition Awesomeversary T-Shirt for free.  All you have to do is make at least a 10 dollar purchase and this cool T-Shirt is yours.

They also have a sweepstakes going on as well with the grand prize being a $1200 dollar Think Geek shopping spree, the Taun Taun Sleeping Bag Prototype, your picture on the Think Geek Homepage, a batch of cookies made by the Think Geek Staff and a random box of doodads.  A awesome prize package from Think Geek!

My favorite Think Geek products over the years have been the Caffeine Molecule Mug, Penguin Mints, The Tux Golf Shirt and Bawls.  What us your favorite Think Geek product?
