Sales departments everywhere will fight tooth and nail to defend their disproportional power over not only volume but also margin. Who would they be, if they would only be offering subtle personal favors for orders, and never receive any for favorable conditions? It's a matter of balance!

Sorry for my sarcasm, I do understand that outside of consumer goods and commodities, price determination is basically unsolved. But I stand to my point: any possible solution that undermines the grandeur of sales departments will be met with hostility.
