Nest 3rd-Generation Learning Thermostat for $171 + free shipping

Altatac via Rakuten offers the 3rd-generation Nest Learning Thermostat in Stainless Steel for $200.95. Coupon code "HOME20" cuts it to $170.95. With free shipping, that's the lowest price we could find now by $42, although we saw it for a buck less three days ago. Improving on its predecessor with a slimmer profile and bigger display, this thermostat "learns" how you set your home's temperature, downloads data, and can be controlled from your smartphone via WiFi. Deal ends June 25.

Note: This coupon can only be used once per account. (You must be signed in to use it.)
