Buying more than one at a time is the smartest way to save on smart plugs. A single plug can cost up to $20 to $25, but you can usually earn a nice discount by picking up a two-pack or four-pack.

For example, Aukey’s Mini Wi-Fi Smart Plugs four-pack is currently being sold for $47.99 via Amazon, down to $12 per plug. You can even save an additional $12 on this purchase by using promo code MD3OVRP8 during checkout, taking your total down to $35.99. That’s one of the best prices for the package that snags these smart plugs for just $9 each.

These well-rated smart plugs support voice assistants like Amazon Alexa or Google Assistant. The free-to-download Aukey Home app lets you activate and deactivate home appliances and electronics from anywhere in the world. Turn on your light automatically, flip it on and off at random intervals when you’re on vacation, schedule your coffee timer to go off, or use your voice to turn off the box fan that keeps you lulling back to sleep. You need no bridge, hub, dongle, or anything else to make them work. Only the Wi-Fi network.

The smart plugs from Aukey will lift the IQ of your home without putting a huge dent in your bank account. They’re compact as an added bonus, so adjacent outlets stay usable. Your purchase includes a 24-month warranty.
