No. All dealers should work to the same high standards.
It is said that bricks and mortar dealers add value by giving objective and useful advice to customers and that justifies their sticking to list pricing and not discounting (as well as the cost of their bricks and mortar, of course). But can we be sure that advice is really objective and useful when they have so much skin in the game.
eg Advocating a more expensive component when a cheaper one is just as good or better.
eg Advocating a component where the dealer's gross margin is larger.
eg Advocating a component that will take the dealer's sales of that marque over a super-commission threshold.
Gotta have a busload of faith to get by?
