TigerDirect offers the Logitech MKZ260 Wireless Desktop Keyboard and Mouse Combo, model no. 920-003042, bundled with a pair of USB speakers, for $39.99. This $20 mail-in rebate cuts it to $19.99. With $4.05 for shipping, that's the lowest total price we could find by $1, although we saw it for $1 less a week ago, since expired. (Most stores charge $40 or more.) This mouse and keyboard set features full-size keys, eight hotkeys, 2.4GHz wireless connectivity, and more. The USB speakers feature a mute button, volume control, and more. Rebate ends September 30.
