All of us get bombarded by volume marketing gimmick at the grocery store with a sale of some quantity of items for some amount. In most cases, you pay the same individual unit price regardless of how many you buy.
For example, if something is four for a dollar, you can buy one for 25 cents and do not need to buy four of them to get that individual unit price of 25 cents. Of course, most people end up buying four and pay the full amount and fall prey to the gimmick.
I wondered if same volume marketing gimmick would work for selling cars.
