MegaMacs offers the refurbished Apple MacBook Pro Unibody Intel Core 2 Duo 2.66GHz 15.4" Laptop, model no. MB985LL/A, for $549.99 plus around $22 for shipping. That's $50 below our mention from last week (which included a smaller hard drive) and the lowest total price we've seen for a refurb in any configuration. (It's also only $52 more than the best price we could find for a used unit with only a 320GB hard drive.) It features an Intel Core 2 Duo 2.66GHz dual-core processor, 15.4" 1440x900 LED-backlit LCD, 4GB RAM, 500GB hard drive, Nvidia 9600M GT 256MB graphics, SuperDrive (DVD burner), AirPort Extreme (802.11n wireless), Bluetooth 2.1 + EDR, Gigabit Ethernet, iSight webcam, SD card slot, and Mac OS X 10.10 Yosemite. Deal ends September 16.

A 30-day MegaMacs warranty applies. Note that this item is in "Grade B" condition and may have scratches or show signs of minor wear.
