Yep, they should follow the same "no-haggle" sales technique of Saturn.
I'm not fond of haggling myself, but car dealers, TV providers, internet providers, jewelry stores, alarm companies etc. obviously are. Its so common that some people are shocked when they call to quit and a company allows them to quit without a trip through the retention/haggling department.
As for add a screen, add a box, that's generally considered much easier than adding a cable in an existing house. I suppose Dish could be like Roku and try to get some companies to make Wally TVs, but I think that's easier for Roku with their 80 million subscribers.
