Staples offers the Logitech M510 Cordless Optical Mouse (pictured), model no. 910-001822, for $19.99. Choose in-store pickup to avoid the $9.95 shipping charge. That’s tied with our mention from a month ago (which included shipping, since expired) and $9 under the lowest total price we could find elsewhere. Sales tax is added where applicable. This wireless mouse features a nano-receiver, ergonomic design, and more. It requires two AA batteries, included.
Staples also has the smaller Logitech M505 Cordless Laser Mouse in Black, model no. 910-001321, for $19.99 via in-store pickup. That’s the lowest total price we could find by $4.
