Hi!
I've set up an account at cafepress.com
http://www.cafeshops.com/squeakev
Cafepress is a nice service that allows to set up a small shop for typical mechandising stuff (Mugs, T-shirts, Mouse-pads, stickers...). (see http://www.cafepress.com/cp/info/products/index.aspx)
The nice thing is that it a) costs nothing to set up and b) they do all the work. The prices in the squeak-ev shop are a little higher than base price (.50 - $2), all profits go to Squeak Germany e.V.
There are only 4 products set up because this needs to be testet first. Anyone in the US care to do alpha-testing? They have a 30-day-money-back garantee.
