Target offers the Logitech Wireless Desktop MK235 Keyboard and Mouse Combo for $9.99. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $5 under our May mention and the best price we've seen. (It's a low today by $5.) The keyboard requires two AAA batteries, and the mouse requires one AA battery (all are included).

Update: It's now available for in-store pickup only.
