After listening to an audio clip of Tony Robins interviewing Frank Kern. Frank Kern goes on to say that he prices his products at 8-10 times the cost the product takes to make i.e if the product costs $50 to make he sells it for $400 minimum. Going on to say that you can get it if you just ask for it and it means you don't have to sell as much stuff.
Is this an ethical way of pricing? Why?
