As one of its daily deals, Dell Home offers the Logitech MK550 Cordless Desktop Wave Keyboard / Mouse Combo, model no. 920-002555, for the in-cart price of $39.99 with free shipping. (Amazon and Office Depot have it for the same price with free shipping.) That's the lowest total price we could find by $10, although we saw it for a buck less in January. This ergonomic keyboard comes with a Logitech cordless laser mouse and unifying receiver. Deal ends December 1 at 7 am ET.
