Walmart offers the Microsoft Touch BlueTrack Multi-Touch Mouse
in Black, model no. 3KJ-00001, for $15.99
. Opt for in-store pickup
to avoid the $4.97 shipping charge. That's a slight drop under last week's mention and tied with the lowest price we've seen. (It's also a current low by $7.) This mouse is sensitive to 1-, 2-, and 3-fingered gestures and features BlueTrack technology, 10-foot range, and 1,000 dpi. It requires Windows 7 or 8.
