I have to confess, I was really thrilled when I found out that Thinkgeek had an affiliate program. Thinkgeek is one of those really great sites that takes just one thing and does it really well. In their case, they sell geek and techno toys, shirts, and gadgets.
Check out these shirts!
Note that these are just samples of the kind of thing Thinkgeek sells, but items may go in and out of production! PLEASE don't give me grief if Thinkgeek doesn't have these particular items anymore by the time you go looking for them!
And not just those. They have some really neat generic toys for around the house and for your cubicle at work. Be sure to check them out
