I have used Kasa Smart Plugs in my house for the last few years... and right up to my most recent purchase from Amazon for $9.99 for a  mini smart plug that they are now selling for $17.99   I just signed on to Amazon to purchase one more smart plug to control my x-mas lights...   I'm very disappointed that Amazon and the sellers have chosen to double the prices on all smart plugs...  I will not buy more smart plugs until after the holidays and hopefully their price gouging will end...  Shame on them....
