Google spent a hefty $3.2 billion on Nest back in January, so it only makes sense that the company would want to sell Nests signature thermostat through its own storefront. And its doing just that starting today, with the $249.99 Nest Learning Thermostat now listed on Google Play. Thats the same price youd pay Amazon, Best Buy, Apple (yes, its still selling Nest for now), or Nest itself for the thermostat, so dont expect any savings from Google. Since Nests mission is to help consumers use energy more efficiently, Google is tying its latest store addition to Earth Day.
