Not really my point.
My point is that if a large company establishes "standard" pricing there will be areas where it works well, and areas where it doesn't. The big problem, which I guess I didn't touch on, is that the sheeple will just spout whatever price they are fed by a big company without thinking about the realities of the areas in which they live. "What do you mean that you won't install my bathtub for the Amazon price just because I live up a 100' flight of beautiful artistic rock stairs and the house has the original lead plumbing in it."
But like so many other things, the service is tailored to densely packed cookie cutter regions and will be force fit to areas that are outside the norms.
