The TP-Link Smart Plug has just gone on sale for $20.96 on Amazon. The discount does not appear on the product page, but you’ll see the sale price when you go through checkout. This is the second lowest price I’ve ever seen for this smart plug, second only to when it was briefly available for $18 through an Alexa exclusive deal this past Cyber Monday. This switch can be directly controlled by Alexa without needing any hubs or other equipment. Just plug it in, set it up in the app, and you’ll be able to control it by saying “Alexa, turn on/off the [selected name].” To receive the discounted price, the plug must be purchased from the seller Network Giant.
