Tekreplay via eBay offers the refurbished 2.4-lb. Apple MacBook Air Intel Core i5 1.6GHz 11.6" Laptop for $299.97 with free shipping. That's $15 under our mention from last November and the lowest price we've seen. (It's $70 under the best we could find for a refurb today.) It includes an Intel Core i5-2467M 1.6GHz Sandy Bridge dual-core processor, 11.6" 1366x768 LED-backlit LCD, 2GB RAM, 64GB SSD, AirPort Extreme (802.11n wireless), Bluetooth 4.0, Facetime camera, and Mac OS X 10.7 Lion.

Note: A 60-day warranty applies, although it's unclear who backs it.
