This Nest 2nd Generation Learning Thermostat drops from $199.99 to $159.99 at Verizon Wireless. Plus, shipping is free making this the best price we found by $39 for this generation. This thermostat allows you to monitor your home's temperature from anywhere. It learns your schedule and adjusts the temperature while you are not home to save energy and money. Editor's Note: I own a Nest and have definitely seen a savings on my monthly bill. I also like how I can control the temperature of my home when I go on vacation. It was also very intuitive to set up and I highly recommend this product. Sales tax is not charged in most states.
