Best Buy offers the Logitech K400 Wireless Touch Keyboard, model no. 920-003070, for $19.99 with free shipping. (Walmart charges the same with free in-store pickup.) That's tied with our mention from last week and the lowest total price we could find by $8. Features include a 33-foot wireless range, built-in 3.5" touchpad, and media hot keys.
Update: As a reader found, Amazon offers it for the same price with free shipping for Prime members.
