This deal has ended.
Update: this is in-stock again and now only $12.95. Amazon now has the La Crosse Wireless Temperature Station (model WS-7013BZ) for just $12.95. The weather station displays indoor and outdoor temperatures as well as date / time. I bought one of these during a previous drop to this price level: it is a fun little toy and I get to know exactly how cold it is without actually going outside. Shipping is around $6 or free if you spend $25.
