Amazon has discounted the August Smart Lock (3rd Generation model) to just $135, that brings the price down from $150. That's not a huge price decrease, but seeing as this smart lock only went on sale a few months ago, it is one of the first times it has been discounted. Making it a great time to pick one up.
The August Smart Lock makes your front door smarter. You can still use your existing key to unlock the door of course, but you will also be able to go ahead and use your smartphone to unlock the door. There are also alerts you can set for those that might be trying to get in, as well alerts for when your kids get home from school and such. August can also be set up so that when you arrive back home, it unlocks the door. This comes in handy when you are coming home with a handful of groceries, as you won't need to fumble around for your keys. Which is very useful, to say the least. The August Smart Lock is very simple to install, August includes all of the necessary instructions in the box, including tape to keep the front lock on the door and makes it easier to install. This won't be its price for long, so you'll want to grab it before it's gone.
