JemJem offers the refurbished Apple MacBook Pro Core i7 Quad-Core 2.3GHz 15.4" Laptop for $629.99 with free shipping. That's $171 under last September's refurb mention and the best price we've seen for this model. (It's also $159 below the best price we could find for a refurb today.) It features an Intel Core i7-2820QM 2.3GHz Sandy Bridge quad-core processor, 15.4" 1680x1050 LCD display, 4GB RAM, 750GB hard drive, AMD Radeon HD 6750M 1GB graphics, 802.11n wireless, Bluetooth, Gigabit Ethernet, SDXC card slot, and OS X 10.6 (Snow Leopard). Deal ends May 13.
