Newegg offers the refurbished Netgear N600 Dual-Band 802.11n Wireless Gigabit Cable Modem and Router, model no. C3700, for $89.99. Coupon code "EMCEGFM33" cuts that to $67.49. With free shipping, that's the lowest total price we could find for a refurb by $22 and $38 less than what you'd pay for a new one today. This 2-in-1 dual-band (2.4GHz and 5GHz) wireless router features a DOCSIS 3.0 modem with speeds of up to 340Mb/s, two gigabit Ethernet ports, USB, and WPA and WPA2 encryption. Deal ends February 21.

A 90-day warranty applies, but it's unclear who covers it.
