Amazon currently has a 2-Pack of Conico WiFi Smart Plugs on sale for $19.49 after applying coupon code IMEZ9PZB at checkout. That is the lowest price I’ve ever seen for smart plugs that can be controlled by Alexa. Unlike most smart plugs, these are compact enough to not block adjacent outlets. I have no experience with this brand and don’t know if these plugs are any good. Reviews seem to be decent at a 4.2 star rating from 209 reviewers.
