How is that even legal? Where is the Federal Trade Commission? I know its time honored tradition etc. People in different markets get different prices too. MSRP is never a starting point. Invoice is. And even Invoice is a scam number.
I guess that's why they have MSRP, to make it all legal. I doubt anyone pays above MSRP, it's just how much one was able to bargain down. The other point is being able to customize the order, and up-sell additional profit centers.
It's one big psychological game, and the successful salespeople are those who know the game well, and how to apply it (differently) towards different audiences. They make the buying an emotional decision, and then help justify that decision with logic where needed. And THAT is why there are differences between the various demographics.
