Walmart offers the TP-Link Kasa Smart WiFi Plug Mini 2-Pack for $29.97. Opt for in-store pickup to dodge the $5.99 shipping charge, or pad your order over $35 to bag free shipping. That's tied with our mention from two weeks ago and the lowest price we could find by $6. These plugs allow for remote control and scheduling via the Kasa mobile app. They're also compatible with Amazon Alexa and Google Assistant for voice control.
