Sears offers the Logitech MK270 Wireless Desktop Keyboard/Mouse Combo, model no. 920-004536, for $17.99. (Amazon charges the same.) Even better, Shop Your Way Max members bag free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $5.99. In-store pickup is also available.) That's tied with our mention from three weeks ago and the lowest total price we could find by $4. This mouse and keyboard set features 2.4GHz wireless connectivity, eight hot keys, and spill-resistant keyboard. It purports to have up to two years of battery life for the keyboard and one year for the mouse.
