Newegg offers the factory-refurbished Netgear 802.11n Wireless USB 2.0 Adapter, model no. WNA3100, for $12. This $10 mail-in rebate drops it to $2. With $1.99 for shipping, that's the lowest total price we could find for a refurb by $6, although we saw it for $0 after rebate last year. (It's also $19 below the best price we could find for a new one.) It features up to 300 Mbps data transfer rate, and desktop stand. A 30-Day Netgear warranty applies. Deal expires May 31.
