NeweggFlash offers the refurbished Logitech M185 Wireless Optical Mouse in Gray, model no. 910-003922, for $5.49 with free shipping. That's a buck under our September mention of a refurb and the lowest total price we've seen for this model. (It's also a current low by $7.) This 2.4GHz portable mouse features a nano receiver and requires a AA battery. Deal ends November 21 at 5 am ET.

A 90-day warranty applies, but it is unclear who backs it.
