MacMall cut prices on select Apple MacBook Pro and MacBook Air Notebooks as part of its 72-Hour Kickoff Sale, with prices starting at $949.94. With free shipping, that cuts several newer models to all-time price lows. Deal ends August 27.

A best bet is the 2.4-lb. Apple MacBook Air Intel Ivy Bridge Core i5 1.7GHz 11.6" Widescreen Notebook, model no. MD223LL/A, for $949.94 with free shipping. (B&H Photo-Video charges a penny more.) That's the lowest total price we could find by $15, outside the price below. This latest MacBook Air includes an Intel Core i5-3317U 1.7GHz Ivy Bridge dual-core processor, 11.6" 1366x768 LED-backlit widescreen LCD, 4GB RAM, 64GB SSD, AirPort Extreme (802.11n wireless), Bluetooth 4.0, Facetime webcam, Thunderbolt port, and Mac OS X 10.8 Mountain Lion.

Note that MacMall lists both Lion and Mountain Lion as the OS; if the shipped item doesn't come with 10.8 installed, it will qualify for a free upgrade.
