Best Buy offers the Logitech M505 Cordless Laser Mouse in Black, model no. 910-001321, for $19.99 with free shipping. That’s the lowest total price we could find for this mouse in any color by $4, although we saw it for $5 less with a rebate back in November. Sales tax is added where applicable. This 2.4GHz wireless mouse features a unifying nano receiver, side-to-side scrolling, and more.
