Newegg offers the D-Link AC Smartbeam 802.11ac Wireless Gigabit Router, model no. DIR-868L, for $89.99. Coupon code "AFNJ1781" cuts it to $59.99. With free shipping, that's $60 below the lowest total price we could find for a new unit. It features 2.4GHz and 5GHz frequencies, four Gigabit Ethernet ports, and WPA2 encryption.

Of note, for an even steeper discount you can add two to cart for $139.18 before the above coupon, $79.18 after. With free shipping, that's only $39.59 per router and $161 under the best price for two new ones purchased elsewhere. A 90-day warranty applies, but it's unclear who backs it.
