Best Buy via eBay offers the Logitech M325 Wireless Laser Mouse in Purple Swirls, model no. 910-002963, for $9.99 with free shipping. That's tied with our mention from last week as the lowest total price we've seen for this mouse in any color. (It's also a current low by $9.) This mouse's wireless receiver features a compact design so it can be left in a laptop's USB port. It requires one AA battery (included).
