Firemall LLC via Amazon offers Prime members the refurbished Linksys by Cisco 802.11n Wireless 4-Port Router, model no. WRT120N, for $14.99 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $9.29.) That beats our mention from three weeks ago for a refurb by $2 and is the lowest total price we could find today for a refurb by $2. This router features four Ethernet ports and both WPA2 and WEP security.

A 3-month warranty applies, although it is unclear who backs it.

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