If you're tired of the crazy weather patterns and walking into a house that is the wrong temperature, you need to get a smart thermostat now. The ability to control the temperature in your home from anywhere using your smartphone is amazing, and right now Amazon is offering Nest's Smart Learning Thermostat for only $200, a savings of $50 off its normal cost.

Several other retailers have dropped its price down to $200 as well, such as:

While $200 may seem like a big investment to replace something in your house that still works, you'll also want to think about the long-term savings potential here. With Nest's learning feature you may be able to reduce the costs associated with heating and cooling your house by up to 30%, which means it could eventually pay for itself over time.

It's also worth mentioning that some retailers have different colors of the Nest Learning Thermostat on sale. While Amazon has only Copper available currently, Best Buy has the options of Stainless Steel, White and Black as well.
