Echo speakers and smart plugs go together like Rafa Nadal and red clay, and now you can get one of each for just $51. That’s only $1 more than the regular price of Amazon’s Echo Dot (though it’s currently on sale for $40), and TP-Link’s smart plug has been a hit with our readers for several years now.
