Interesting. I might do some research and see if what you ordered would work for me. Thanks for sharing! 
I use WEMO WiFi smart outlets. Only has one receptacle, but you could connect an extension cord as long as the load doesn't exceed it's rating.
At night, my bedroom and living room lights go on at preset times. I also have a bug zapper that goes off at bedtime so I'm not listening to bugs getting zapped.
As long as you can get a WiFi signal wherever you plug them into your home's wiring, any brand would work.
I had to "install" an Alexa "skill" to communicate with the WEMO devices. Now I turn off the light over my bed with a voice command, or on dark days like today, i turned on the lamp over the couch the same way. Really convenient.
TP-link has one for $11, or a 3-pk for $26.99. with Prime shipping. I have no experience using them, but one big selling point is it can be connected to most home automation hubs, such as Alexa, Apple Home, Google Home and Samsung SmartThings. You can also find those that can monitor energy used at that outlet. The biggest thing is ease of set up.
WEMO can be a bit tricky, having to install skills on Alexa, setting up a WEMO account, registering the devices in the WEMO app, then setting them up with schedules in the Alexa app. Once in a while, I have to delete them from the Alexa app and redo them because Alexa can't communicate with them. Probably due to "upgrades" from Amazon.
