Where the quality gets compromised or the deal gets nasty or a good service model goes under-nourished?
When the buyer is more bothered about how much the seller is earning than how much the buyer himself is saving.
Further, all buyers will not know the overheads, risks and costs of the seller. Still the intent is to make a statement, have analysis and conclusions basis partial knowledge to negotiate and expose the levels of self-understanding. Irony of the system.
