Best Buy offers the Logitech M315 Cordless Optical Mouse in Silver (pictured), Colt Matte, Violet Splash, Steel Blue, or Brilliant Rose for $14.99 with free shipping. That's the lowest total price we could find for any color by at least $6, though we saw it for $2 less three weeks ago. Sales tax is added where applicable. This 2.4GHz wireless mouse features a nano-receiver.
