Tekdeals via eBay offers the refurbished 2.4-lb. Apple MacBook Air Intel Core i5 1.6GHz 11.6" Laptop for $299.99 with free shipping. That's tied with our January mention as the lowest price we've seen. (It's $9 under the best price we could find for a refurb today, although most merchants charge at least $349.) 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 10.10 Yosemite.

Note: A 30-day warranty applies, although it's unclear who backs it.
