NeweggFlash offers the refurbished Logitech K400 Wireless Touch Keyboard, model no. 920-003070, for $16.99 with free shipping. That's tied with our mention from last month and $8 under the lowest total price we could find for a new one. It features a 3.5" touchpad, 33-foot wireless range, and media hot keys. Deal ends August 29.
A 90-day warranty applies, but it's unclear who backs it.
