The point I'm making is that a buying decision depends on much more than just the price you're paying. All kinds of information go into people's decision-making process. For instance, if you knew that the duck-fur coat (or whatever, I don't know if that's a real thing) you are about to buy was made by torturing ducks, you would be less likely to buy it, even if the price, by itself, was reasonable. This is why a lot of companies that sell animal products go to great lengths to keep such information from consumers: because the resulting information asymmetry benefits them. The idea that at the end of the day the product/service is either worth it to you at X price or it isn't is simply wrong.
