I am not having any luck getting the smart plug for 4.99. I ordered via alexa as prompted. In the small print it says that the discount will be shown and there in the checkout so I finished checkout with alexa as she offered. She said the $20 discount, but when I checked my order, I was charged teh full 24.99 using mostly my giftcard. No mention anywhere of any $20 off. So I cancelled the order. I just put it in the cart again via Alexa, she said again including the prime discount. This time I checked first and its in the cart still not showing any discount. I don't want to go through with purchase again in case I can't catch the cancel anymore. It often goes fast to processing order. I will not call them so I guess that one is a bust.
