The Dutch media chain store Free Record Shop have recently started selling ebooks ereaders. They’re currently selling 16 ereaders as well as a tablet. They have models from most of the major manufacturers as well as models both with and without Wifi and touchscreens. They even sell the Cool-ER (for 200 euros, hah).
According to my source, they will also soon be selling ebooks. I’m having trouble finding that info on the website so I don’t know for sure. My Deutsch is lacking. (kidding)
