Best Buy offers the Microsoft Wireless Mobile Mouse 3500 in Sangria Red, model no. GMF-00134, for $9.99. With free shipping, that’s the lowest total price we could find by $8. (We’ve seen it for the same price or slightly less in several other colors in the past few months.) Sales tax is added where applicable. This wireless mouse features BlueTrack technology (which purportedly works on more surfaces than optical or laser technology), a nano transceiver, on/off switch, and more.
