Price Lining

I was looking at a buying a new car the other day and saw a perfect example of price lining. With a tons and tons of combinations, there was seperate prices for each. Leather, for instance was additional, the type of sound system, even sunroof vs. moonroof options. Almost everything you can think of as an additional feature came as an option but not without raising the price of course. It's very smart if you think about. Advertising a car at a good price to get people interested and then showing them all of the other available options for extra prices and before you know it, you have spent much more on a car than you had initially planned.
