The Apple Store offers a selection of factory-refurbished MacBook Air laptops, as listed below. Plus, each qualifies for free shipping. At up to $300 off, that's tied with our mention from three weeks ago as the lowest total price we could find for these systems. Each carries a 1-year Apple warranty, the same as new units. Items are removed from The Apple Store when sold out. Note that these systems are eligible for the OS X Mountain Lion Up-to-Date Program. Notables:
