I think there are a list of different prices where the parts person can quote any of them. They do it based on what they think you will pay. At Alderson in Lubbock, I had made several visits there where I was quoted outrageous parts prices over MSRP. The parts specialists then made the realization that I was smarter than I looked (a man in a suit) and then began quoting MSRP. Since they don't sell parts below MSRP, I buy parts at Moritz when I am in town.
