MegaMacs offers the refurbished 4.5-lb. Apple MacBook Pro Intel Core i7 2GHz 15.4" Laptop, model no. MC721LL/A, for $549.99 plus around $20 for shipping. That's $152 under our July refurb mention (which only had 4GB RAM; this one has 8GB) and easily the lowest total price we've seen for this model in any configuration. (It's also $199 under the best price we could find for a refurb with just 4GB RAM today.) It features an Intel Core i7 2GHz quad-core processor, 15.4" 1440x900 LED-backlit LCD, 8GB RAM, 500GB 7200 rpm hard drive, SuperDrive DVD Burner, AMD Radeon HD 6490M 512MB video card, AirPort Extreme (802.11n wireless), Bluetooth 2.1+EDR, Gigabit Ethernet, iSight webcam, multi-touch trackpad, SD card reader, and OS X 10.10 (Yosemite). Deal ends September 30.
