Newegg offers the refurbished Logitech MX Master Wireless Mouse
in Black for $39.99
with free shipping
. That's $10 under last week's mention of a new one and is the lowest price we've seen for this mouse in any condition. (It's also $20 under the best deal we could find today for a new one.) Features include a 1,000 dpi movement resolution, speed-adaptive scroll wheel, and rechargeable battery with up to a 40-day life per charge. Deal ends November 20.
Note: A 90-day Newegg warranty applies.
