Costco offers its members the 3.96-lb. Lenovo ThinkPad Yoga Intel Haswell Core i5 1.6GHz 12.5" Touchscreen Ultrabook, model no. 20CD0032US, bundled with a $25 Microsoft Windows Store Gift Card and a download code for Kapersky Internet Security 2013 1-User for Windows, for $899.99 plus $29.95 for shipping. (Non-members pay $46 more. The software will be added to your cart automatically.) Assuming you'll use the gift card, that's $195 under last month's mention and the lowest total price we've seen for any Lenovo 12.5" laptop with an Intel Core i5-4200U processor. (It's also a current price low by $145.) It features an Intel Core i5-4200U Haswell 1.6GHz dual-core processor, 12.5" 1920x1080 (1080p) multi-touch LCD, 4GB RAM, 128GB SSD, 802.11n wireless, Bluetooth, webcam, media card reader, USB 3.0, HDMI, 8-cell battery, and Windows 8.1.
