A few months ago, we started a CafePress store for selling t-shirts, sweatshirts, coffee mugs, etc. At some point we will start making this stuff ourselves and sell direct, but for now this is the easiest solution. There are several sections in our store, including Pineapple Racing Logo items, Felix Wankel items, Rotary Engine Illustrated items and even a little Ninja character that one of our employees girlfriends came up with. Suprisingly, the Ninja character sells circles around the other stuff. We sold $425 worth of Black Ninja shirts last week alone!

Let me know what you think and if you want a special design, I may be able to accommodate your request.
