Best Buy offers the Logitech K810 Bluetooth Keyboard, model no. 920-004292, for $49.99 with free shipping. (Amazon offers it for the same price.) That's $10 under our mention from four weeks ago and the lowest total price we could find now by $26. (For further comparison, we saw it for $5 less in July.) It features illuminated keys with a hand-detecting light sensor, wireless range of up to 30 feet, and USB charging cable.
