Walmart offers the Logitech MK360 Wireless Compact Keyboard for $15.17. (Amazon has it for the same with free shipping for Prime members.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from a week ago and the lowest price we could find now by $10. This keyboard features 12 programmable F-keys, six hot keys, and a 3-year battery life. Two AA batteries are required (included).
