We've been spreading the smart plug gospel for months. Smart plugs are one of the easiest ways to retrofit your home to work with newer, more intelligent tech. Thanks to this deal, they're affordable too. B&H has two TP-Link HS107 Wi-Fi Smart Plugs on sale for $39.99 shipped, saving you $20 off the usual price. Shipping is free. Considering one plug is $30 at Amazon, this is a total steal. You have to be quick, though, as the deal is only good for today.

These smart plugs each have two outlets so you can transform one AC outlet into two. They connect to your Wi-Fi network, so setup is simple. Each plug allows you to turn your electronics on or off from anywhere in the world using the free Kasa app for your iOS or Android device. You'll be able to see if you left something on while you're away from home, or schedule a device to turn on just before you arrive back from a trip. These are great too because they're small enough where you can plug two into the same wall receptacle, unlike other bulkier smart plugs which obstruct the unused outlet. You can control them with the free app, or with your voice if you have an Alexa or Google Assistant gadget around.

Existing owners rate TP-Link smart plugs very highly with an average of 4.3 out of 5 stars based on over 15,600 reviews at Amazon.
