For now, we only have a coffee mug on Cafe Press. Stay tuned.
UPDATE: We uploaded this image to Cafe Press as a bumper sticker, and they blocked its usage for products within thirty minutes. You can still get the WTF, California mug while we set up an account with another service. And on a related note, did you know there really IS a WTF, California?
