Walmart offers the Logitech M185 Wireless Optical Mouse in Black, model no. 910-004426, for an in-cart price of $8.97. Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. That's $1 under our mention of a different color from last week and at least a buck less than you'd pay for any color at another local retail store. It features a nano receiver, scroll wheel, and includes one AA battery.
