Best Buy has a heck of a deal on one of Logitech’s best mice: the Logitech MX Revolution. The retailer is selling it for just $50. That’s $25 less than Amazon is selling it for and 50% off the MSRP. Good deal? Yup. Good mouse? Everyone says so. Just remember that Nicholas Deleon was singled out and persecuted by Best Buy when you’re saving that cash.
