Good Guys Electronics via Rakuten offers the Nest Learning Thermostat E for $125.50 with free shipping. That's tied with an expired mention from three weeks ago as the best price we've seen. (It otherwise goes for at least $169 elsewhere.) It features a 320x320 1.8" 24-bit color LCD, four sensors (temperature, humidity, proximity, and ambient light), built-in 802.11n wireless, Bluetooth, and compatibility with most 24-volt heating and cooling systems.
