For people living in Germany this might be an interesting offer. Thalia, the shop who introduced the Sony Reader in Germany some time ago, will sell a limited number of used Sony Readers for 179,99€. The readers were used to train Thalia employees and have been tested and reset and come with the usual warranty. The price for a new one is 249,00€, so the offer is not too bad.
Sales will start on Oct. 04 and will last until supplies run out. Go here for more info on the Sony Reader sale at Thalia.
