Ending tonight, TigerDirect offers the Logitech K800 Wireless Illuminated Keyboard, model no. 920-002359, for $79.99. This $25 mail-in rebate cuts it to $54.99. With around $5 for shipping, that's the lowest total price we could find by $18, although we saw it briefly for $20 less in September. It includes illuminated keys with hand-detecting light sensor, micro-USB charging cable, and more. Rebate expires today.
