Via select Alexa-enabled devices and for Prime members only, Amazon offers the Belkin WeMo Wi-Fi Switch Smart Plug for iOS and Android, model no. F7C027fc, for $19.99 with free shipping. (To order, say, "Alexa order WeMo smart plug." The link is for reference only.) That's $8 below our Cyber Monday mention (which included a $10 eBay gift card) and is lowest outright price we've seen. (It's the best deal now by $10.) The switch operates over WiFi and mobile Internet to turn electronics on or off from anywhere. It's compatible with smartphones or tablets running Android 4.1 and higher or iOS 8 and higher and works with Amazon's Alexa-enabled devices via voice control.
