I'll be willing to listen to any plans that you might have. When I had a couple of computer stores, I would have sheets printed out with all the components necessary to build a computer and the prices. When a customer came in the store, I would ask questions like how fast a processor they would like, how much memory they would like, how large a hard drive they would like etc. As I would go down the list, the customer could buy exactly what they wanted. In contrast, most other stores had 3 or 4 models they would sell with no option to deviate.

The message is that it is essential to find out what a customer wants. Once you have determined what people want to buy, it is a question of how much they will pay.
