The Apple Store offers its factory-refurbished Apple MacBook Air Intel Haswell Core i5 1.3GHz 11.6" Laptop, model no. MD712LL/A, for $809 with free shipping. That's tied with last week's mention as the lowest total price we've seen for this model. (It's also $90 under the best price we could find for a new unit.) It features an Intel Core i5 1.3GHz Haswell dual-core processor, 11.6" 1366x768 LED-backlit LCD, 4GB RAM, 256GB SSD, 802.11ac wireless, Bluetooth 4.0, Thunderbolt port, two USB 3.0 ports, and Mac OS X. It includes a 1-year Apple warranty (the same as new units).
