You can buy T-Shirts and Mugs from our Merchandise Store on CafePress.com.

Unfortunately, the prices at CafePress are rather high, so currently we are not even marking up the price at all, you get it at our cost. If you don't know what CafePress is, they are basically a site that lets you upload artwork and create a "Store". You can define all kinds of products using your artwork, like t-shirts, mugs, mouse pads, etc and they have operations to produce the merchandise on the fly. That is, they don't keep inventory of t-shirts with your artwork silkscreened, they print a shirt when the order comes in, same with mugs and all their products, they produce it on demand. They handle the shipping and ecommerce and it costs you $5/month to have a store (or they have a very limited free store which we are using). I imagine that a lot of their business is just poeple wanting to make their own custom one off products for themselves and very few of the "Stores" move a lot of product, so they charge a bit more because even with automated processes its still slows you down if you only produce one offs. If you start moving a lot of product I imagine you begin to get better negotiations on the cost. For now, we're just happy if you want to wear a mojoPortal shirt or drink from a mojoPortal mug! Thanks for helping us spread the word about mojoPortal.
