TigerDirect offers the factory-refurbished Netgear 802.11n USB 2.0 Adapter, model no. WNA1100-100ENS, for $9.99. This $10 mail-in rebate cuts it to $0. With $2.29 for shipping, that's $17 under the best price we could find for a new one, and the lowest total price we've seen for this adapter (new or refurb) by $3. It includes an adapter cradle for desktop computers. A 30-day Netgear warranty applies. Deal ends March 28.

Not one for rebates? TigerDirect via eBay still has it for $7.99 with free shipping. It's the best non-rebate price we've seen for this adapter.
