TigerDirect offers the factory-refurbished Linksys 802.11n Wireless 4-Port Router, model no. WRT120N, for $29.99. This $20 mail-in rebate cuts it to $9.99. With $2.99 for shipping, that's $7 under last month's mention of a refurb and the lowest total price we could find for a refurb by $10. (It's also $33 below the best price we could find for a new unit.) This router features four Ethernet ports and both WPA2 and WEP security. A 90-day Linksys warranty applies. Deal ends April 11.
