B&H Photo Video offers the Keewifi Kisslink WiFi Smart Plug Mini 2-Pack for $19.95 with free shipping. That's $10 under our September mention and the lowest price we've seen. (It's also the lowest best we could find for this quantity by $12.) Via the free Kisslink app, each plug allows you to turn devices on and off remotely and set customized and preset schedules. They also feature voice control via Amazon's Alexa.
