Best Buy offers the refurbished Apple Wireless Bluetooth Keyboard, model no. MC184LL/B, for $29.99 with free shipping. That's tied with our refurb mention from January as the lowest total price we've ever seen for this keyboard. (It's also $32 less than the best price we could find for a new unit now.) Sales tax is added where applicable. This ultra-thin keyboard features an aluminum enclosure and Bluetooth connectivity. It requires two AA batteries (included). Update: Sold out.

Of note, Best Buy also offers the refurbished Apple Keyboard with Numeric Keypad (pictured), model no. MB110LL/B, for $21.99 with free shipping. That's $17 under our mention of a used unit from last June and $26 below the lowest total price we could find for a new one today. This wired ultra-thin keyboard features a numeric keypad, two USB ports, and more.

Note that these items are sold "as-is" and no warranty applies, although Best Buy's return policy does apply.
