Did you know that Wikibooks has a store on CafePress? It has had one for a while, but the selection was relatively small and all the things there used the old logo.
Today I'm pleased to announce that, with help from Jay Walsh and Cary Bass, the Wikibooks store has been updated to use the new logo, and an expanded list of Wikibooks products! All the old products with the old logo are still there too, if you're into that vintage look. Proceeds benefit the WMF, of course.
