Staples offers the Logitech MK270 Wireless Desktop Keyboard and Mouse Combo for $14.99. Plus, Staples Rewards members bag free shipping. (Not a member? It's free to join.) That's the lowest price we could find by $7, although we saw it for $2 less in March (via pickup). The set features 2.4GHz wireless connectivity, with a range of up to 30 feet. The full-size keyboard features eight shortcut buttons, a number pad, and up to 24-month battery life. The compact mouse features up to a 12-month battery life.
