Altatac via Rakuten offers the refurbished Logitech Ultrathin Keyboard Cover for iPad in Black, model no. 920-004013, for $19.99 with free shipping. That's the lowest total price we could find for a refurb by $5, although we saw one for $2 less last month. This aluminum keyboard is 8mm thick, doubles as a stand, and includes a USB port with charging cable. It's compatible with 2nd-, 3rd-, and 4th-generation iPads.
