Kohl's offers the third-generation Nest Learning Thermostat for $199.99 with free shipping. Pad your order over $200 to earn $40 in Kohl's Cash. (It can be redeemed in-store or online from July 5 to July 19.) Assuming you'll use the credit, that's the lowest price we could find by $40 (outside of the deal below), although we saw it for $11 less in November. 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 July 4.
