Prime Day is over--but you can still get these great deals if you act fast

Amazon's October Prime Day (aka Prime Big Deal Days) officially ended Oct. 9, but that doesn't mean every deal is done. Some companies have extended the discounts on their gear a little longer, and many no longer require you to have an active Amazon Prime subscription to take advantage of them. Some are still Prime subscriber exclusive, though, and if that's the case, you can sign up for a free 30-day trial here if you don't have one. However, you should add to cart now; there's no telling how long any of these discounts will last since they're no longer tied to an official sale. Google's Nest Thermostat is a particularly good Prime Day deal because it can actually help pay for itself over time. The Wi-Fi-enabled thermostat can learn your habits and schedule over time and activate your HVAC (Heating, Ventilation, and Air Conditioning) system more efficiently and less frequently.
