What Would the World Look Like Without explain the exceptions to the law of demand?

I’ve found that most of the time, people can’t imagine why they would want something, or are afraid that they will want it. When you go to a store and you see something, you think “Gosh I want that, I want that.” But it turns out that you don’t really want the item anyway. You’re just afraid of the idea of having to buy it. The same is true when you plan to buy something.
