Walmart offers the Logitech K400 Plus Wireless Touch Keyboard, model no. 920-003070, for $17.99. (Office Depot and OfficeMax charges the same.) Choose in-store pickup to dodge the $5.97 shipping fee. That's a buck under our mention from five days ago and the lowest price we could find by $2. It features a 33-foot wireless range, built-in 3.5" touchpad, and media hot keys.
