Staples offers the Microsoft Wireless Mobile Mouse 3500 in Poppy Red (pictured), model no. GMF-00013, or Turf Green, model no. GMF-00108, for $9.99. Choose free in-store pickup to avoid the $9.95 shipping fee. That matches our mention from two weeks ago, which had free shipping, and is the lowest total price we could find now in any color by $7. 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.
