Meritline offers the factory-refurbished Logitech K750 Wireless Solar Keyboard, model no. 920-002912, for $44.99. Coupon code "MLCK88FUNL1" cuts it to $34.99. With free shipping, that's tied with our June mention and the lowest total price we've seen. (It's also $30 less than the best total price we could find for a new unit, although we saw one for $5 more back in February.) This wireless keyboard is powered by light and measures only 1/3" thick. A 90-day Logitech warranty applies.
