As one of its daily deals, Newegg offers the Logitech Wireless Performance Mouse MX, model no. 910-001105, for $44.99 with free shipping. That's tied with our mention from last month and the lowest total price we've seen for a new unit. (It's a current low by $10.) It features four thumb buttons, a scroll wheel, and Logitech unifying receiver dongle. Deal ends today.
