Today only, as a part of its Deals of the Day, Best Buy offers Apple’s 13-inch MacBook Air from $699.99 shipped. Better yet, those with access to student discounts can save an additional $50, bringing the total down to $649.99 for the entry-level model. That’s as much as $350 off and a return to its previous all-time low at Best Buy. You’ll find upgraded configurations on this landing page that are eligible for the same discounts as well.
