TechRabbit offers the refurbished Logitech MX Master Wireless Bluetooth Laser Mouse in Black for $47.99 with free shipping. That's $17 under the lowest price we could find for a new one today, although we saw a refurb for $8 less in November. It connects to up to three computers at once via the included unifying receiver or via Bluetooth. Features include programmable buttons, an adjustable DPI (from 400 to 1,600), speed-adaptive scroll wheel, thumb wheel, and rechargeable battery with up to a 40-day life per charge. Deal ends March 13.

Note: A 1-year TechRabbit warranty applies.
