Amazon offers its Amazon Prime members Logitech M305 Cordless Optical Mouse in Silver, model no. 910-000928, for $11 with free shipping. (Non-members can spend over $25 to qualify for free shipping; otherwise, shipping costs $5.58.) That's $1 under our last week's mention of this mouse in a different color and the lowest total price we could find by $16. This 2.4GHz wireless mouse features a nano-receiver, 1,000dpi tracking, and more.

Amazon Prime membership is $79 per year; however, Prime is free for college students for one year, and free for parents and caregivers for three months.
