Put it this way: If you were selling something, would you like it if someone made a point of publicly posting that your product is more expensive than someone else’s?
Personally, I have a certain kind of business right now. I charge more for my product than many other people do.
But there are maalos to mine. In fact one of the maalos is the fact that it costs more money which can be a maaleh for reasons that I can’t explain right now.
When I am trying to convince people to buy my product, I often point out these things to them. If they would ask me why they should buy my product when they can get something similar for less money, I explain these things to them.
But I would be very upset if someone were to make a point of announcing to the world that I charge more than others do without saying anything else.
