As one of its daily deals, Amazon offers Prime members the Logitech M320 Wireless Optical Mouse in Black, Blur, or Red for $8.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $8.22.) That's a buck under our mention from last July and the lowest total price we've seen. (It's a current best by $4.) It features a USB nano-receiver, wide scroll wheel, rubber grip, and right-handed contoured design. One AA battery is required (included). Deal ends today.
