Have you wanted to purchase the Nest thermostat but the price wasn't quite right? The 2nd generation Nest thermostat saw a $50 price drop, down to $199 courtesy of the 3rd generation being launched by Alphabet a few days ago. The new 3rd generation Nest is thinner, has a bigger display, more sensors and features furnace alert capabilities.
If the upgrades and changes between the 2nd and 3rd gen are not that important to you, the 2nd generation price decrease makes it a more appealing buy for anyone looking to upgrade to a learning thermostat.
Not sure how long this deal may last as once stock runs out it will likely not be replenished.
