I know this is $7 pricier than the GG Commercial deal the other day but this one no membership required yo!
Short and simple. TP-Link Slim Wi-Fi Plugs KP115 $29 @ Scorptec but the catch is delivery / pick up date is unknown.
KP115 is the replacement of the good ol' HS110. Basically WIFI Smartplug with energy monitoring but slimmer profile as the previous one tends to take up more space when plugged in on dual power socket.
