As one of its daily deals, Amazon offers the Logitech K810 Bluetooth Keyboard, model no. 920-004292, for $49.99 with free shipping. That's tied with our mention from last winter and the lowest total price we could find by $42. (For further comparison, we saw a refurb for $7 less in March.) It features illuminated keys with a hand-detecting light sensor, wireless range of up to 30 feet, and USB charging cable. Deal ends today.
