For its Rewards members, Best Buy offers the second-generation Samsung SmartThings Hub in White for $49.99 with free shipping. (Not a member? It's free to join.) That's tied with last year's mention as the lowest price we've seen. (It's the best deal today by $30.) The hub allows you to connect all of your smart locks, lights, outlets, and thermostats and control them with your smartphone via the free SmartThings app. It's compatible with iOS, Android, and Windows Phone.
