Tek Replay via eBay offers the refurbished 2.4-lb. Apple MacBook Air Intel Haswell Core i5 1.3GHz 11.6" Laptop, model no. MD711LL/A, for $479.99 with free shipping. That's $20 under our May refurb mention and the lowest total price we've seen for this laptop in any condition. (It's also $320 below the best price we could find for a new one today.) It features an Intel Haswell Core i5 1.3GHz dual-core processor, 11.6" 1366x768 LED-backlit display, 4GB RAM, 128GB SSD, 802.11n wireless, Bluetooth 4.0, Thunderbolt, USB 3.0, and Mac OS X 10.9 Mavericks.

A 30-day warranty applies, but it's unclear who backs it. This item is noted as being cosmetically "fair" and will show signs of use such as minor scratches, dings, or spots. Want one in better condition? The same seller offers a refurb in "good" condition for $499.99 with free shipping.
