Amazon offers Prime members the D-Link Cloud N750 Dual-Band 802.11n Wireless 4-Port Gigabit Router, model no. DIR-836L, for $29.99 with free shipping. (Rakuten Shopping charges the same. Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $8.84.) That's $15 under our mention from a month ago, the lowest total price we've seen, and a current low by $38. It features four Gigabit Ethernet ports and support for WPA and WPA2 encryption.

Update: It's now sold out at Amazon; however, Rakuten Shopping still offers it for $29.99 with free shipping.
