Most prices fall between the cast of marginal manufacturing and the value to the buyer.

Maximizing profit would indicate selling to everyone at their individual price on the demand curve (limited by marginal costs on the low end).

[P.O.E.]

That would involve keeping the prices secret from other buyers. The free market requires instant, open and public pricing info.

Which is why advertisers and politicians spend so much time obscuring the facts.
