Newegg offers the refurbished Logitech Anywhere MX Wireless Mouse, model no. 910-002896, for $34.99. Coupon code "EMCAXKW27" cuts it to $24.49. With free shipping, that's $15 under the best price we could find for a new unit, although we saw a refurbished one for $2 less in July. It features dual side buttons, laser tracking, and a Logitech unifying receiver. Deal ends September 21.

A 90-day warranty applies, although it's unclear who backs it.
