Amazon has the NETGEAR Nighthawk R6700-100NAS AC1750 Smart Dual Band Wi-Fi Gigabit Router available for a final total of $88.85 after $20 Amazon coupon (discount shows at checkout). It's an older router that looks to be DD-WRT compatible.
Previous deals on this router via SD search shows prices around $100-$89, mostly at costco and a bit ymmv. At $108.85, it's the lowest it has been on Amazon and the $20 coupon reduces it further.
May not be a killer deal but it's not too bad and perhaps the best it has been outside of a Costco.
