After playing a bit with the Amazon echo, I realized that even if Amazon is the leader in online retailing, the echo wasn't able to give the price of anything (except the Echo device itself).
I thought it was one of the question we always think about when we are discussing about a subject with some friends:
For instance when talking about Tesla one the question that directly come is how much is the latest Tesla Model 3?
So instead of using your phone, just ask Alexa!
More over if the item searched is an item available on Amazon, I can even monetize the service thanks to the advertizing partnership that comes with the Amazon affiliate program.
