NeweggFlash offers the refurbished Logitech MK550 Cordless Desktop Wave Keyboard / Mouse Combo, model no. 920-002555, for $28.99 with free shipping. That's the lowest total price we could find for a refurb by $8, although last summer we saw it for $3 less. (It's also $21 under the best price for a new unit.) This ergonomic keyboard includes a Logitech cordless laser mouse. Deal ends June 27.

A 90-day warranty applies, but it's unclear who backs it.
