Geekbuying via Newegg offers the Geekbes WiFi Mini Smart Plug 3-Pack for $21.99 with free shipping. That's $4 under our December mention and the best per-unit price we've seen for a smart plug. (It's also $8 under the best price we could find to purchase three elsewhere.) It features power scheduling, Alexa voice control, and smartphone control. Note: This ships from Asia and may take up to two weeks to arrive.
