Electronics Expo via eBay offers the Altec Lansing Octiv Duo iDock, model no. M202, for $47.75 with free shipping. That's the lowest total price we could find by $2, although we briefly saw it for just $5 in October (a short-lived price mistake). The Octiv Duo iDock allows you to dock, charge, and play two iPhones or iPods at once. Deal ends February 23 at 12:03 pm ET.
