When I search for Ezlo Plus, google shows the price as $39.95, but when I go to the website, the price is $69.95. I cannot find any information on a sale anywhere.
There is a discount I believe for existing Vera customers. Not sure how you claim it. Try contacting them.
I was able to find a thread with a discount for existing customers Ezlo Secure is coming. It seems that $47.95 was the best price offered so far. Not sure how google came up with $39.95.
