I mean this is the point of having salespeople, to maximize the amount of money you get from each customer.

This is why when I go to the price page for a product and seeing "contact our sales team for a quote" I look for an alternative.

Dell does a soft version of this by setting uncompetitive prices on the website and making you call to get the real price, although ironically that usually just means we go with a different company that simply posts a competitive price.
