NeweggFlash offers the refurbished Logitech K400 Wireless Touch Keyboard, model no. 920-003070, for $17.99 with free shipping. That's a buck under our mention from four days ago and the lowest total price we could find for a refurb by $4. Features include a 33-foot wireless range, built-in 3.5" touchpad, and media hot keys.

A 90-day warranty applies, but it's unclear who backs it.
