As one of its daily deals, Amazon offers its Prime members the Logitech K360 Wireless Keyboard in Glossy Black, model no. 920-004088, for $15.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $8.77.) That's the lowest total price we could find by $4, although we saw it in a different color for $6 less in November. It features six 1-touch hotkeys, 12 programmable F-keys, and a USB receiver.
