Early Prime Day deal brings the Amazon smart thermostat down to only 52

Amazon Prime Day hasn't even officially started yet and we are already starting to see a massive influx of deals. For instance, the Amazon Smart Thermostat is on sale for 52. This is a discount of more than 30 percent and the best price we've seen all year. This is one heck of a smart thermostat with a robust list of features. It does require a C-wire or a power adapter kit, and these are sold separately. Once you get it hooked up though, the Amazon Start Thermostat allows for voice control over your climate, thanks to Alexa.
