Kmart offers the D-Link N300 802.11n Wireless Gigabit Ethernet Cloud Router, model no. DIR-636L, for $19.99. Choose in-store pickup to dodge the $6.50 shipping fee. That's tied with our mention from a month ago as the lowest price we've seen. (It's also $35 under the lowest shipped price we could find today.) It features WPA/WPA2 and WPS encryption, four Gigabit Ethernet ports, one WAN port, and USB.

Of note, Shop Your Way Rewards members will earn a Kmart credit with these purchases and may be eligible for additional credits and discounts.
