newegg offers the 3.5-lb. Sony VAIO T-Series Intel Core i5 1.7GHz 13.3" Ultrabook in Silver Mist, model no. SVT13125CXS, with the Everki 13.3" Tempo Ultrabook Case for $699.99. This $100 mail-in rebate drops it to $599.99. With free shipping, that's tied with our Black Friday mention of the laptop alone and the lowest total price we could find by $100. (The previous deal didn't require a rebate, but it also didn't include the case.) It features an Intel Core i5-3317U 1.7GHz Ivy Bridge dual-core processor, 13.3" 1366x768 LCD, 4GB RAM, 500GB hard drive with 32GB hybrid drive, 802.11n wireless, Bluetooth 4.0, webcam, and Windows 8 64-bit. Rebate ends December 19.

Note that no optical drive is included.
