It sounds like you are saying that businesses should only be able to sell services that they publicly advertise with prices. For example, if Coca Cola wanted to have a product placement idk the eventual Jok3r movie, would Warner Brothers would need to advertise that service somewhere on the website? Would you see Coca Cola's advertising department calling WB and being "yo, what do we have to do to get poison ivy to have a fridge full of Coca Cola?" be sneaky?

There are businesses and them there are businesses which have a market dominating position. The latter have to be careful to avoid striking preferential deals only available to them furthering their dominant positin.

Coca-Cola and large movie studios sound more like the latter than the former, though.
