The original Nest Learning Thermostat, (first generation model no. T100577), drops from $229 to $198 when you add it to your cart at Amazon. With free shipping, that's the first and therefore best deal we've seen on this popular thermostat which learn how you like your home's temps and sets your system automatically. This is the same price advertised by Lowe's Black Friday ad, but you can get it here now. Its also features built-in WiFi that allows it to download data and be programmed from your smartphone.
