The Apple Store again discounts several factory-refurbished MacBook Air notebooks, as listed below. Plus, each system qualifies for free shipping. At up to $400 off, most models tie last week's mention and are at the lowest total price we've seen. Sales tax is added where applicable. Each MacBook Air carries a 1-year Apple warranty, the same as new units. Items are removed from The Apple Store when sold out. Some best bets (you may need to scroll to find the model):
