Walmart offers the Logitech K400 Wireless Touch Keyboard, model no. 920-003070, for $19.97. (Amazon charges the same for Prime members.) Choose Site-to-Store pickup to dodge the $4.97 shipping fee. That's tied with our mention from two weeks ago and the lowest price we could find by $10. It features a 33-foot wireless range, built-in 3.5" touchpad, and media hot keys.
