MegaMacs offers the refurbished Apple MacBook Pro Unibody Intel Core 2 Duo 2.6GHz 17" Laptop, model no. MB604LL/A, for $549.99 plus around $22 for shipping. That's $50 below our mention from two weeks ago and the lowest total price we've seen for this model in any configuration. (It's also $178 under the best price we could find for a refurbished model with a smaller 320GB hard drive.) It features an Intel Core 2 Duo 2.6GHz dual-core processor, 17" 1920x1200 LED-backlit LCD, 4GB RAM, 500GB hard drive, NVIDIA 9600M GT 512MB graphics, dual-layer SuperDrive, Gigabit Ethernet, AirPort Extreme (802.11n wireless), Bluetooth 2.1 + EDR, and iSight webcam. Deal ends September 2.

Note: A 30-day MegaMacs warranty applies. It includes an OS, but it is unclear which one is installed.
