I despise firms like carmax, where they promote their "No Haggling" as a feature, whereas I see it as a bug. They're baking in a fixed profit on used inventory and the customer has no option to impact their profitability and reduce acquisition cost. Now that I think about it, I am going to buy long terms puts on their stock,as this event should completely destroy their business.
