Hello everyone. In today's web we will discuss about a very popular marketing technique which is used by many popular people in their life. For example, when the iPad was first launched, Steve Jobs put up a big screen with the price triple and dollars. But after his presentation, the extra time was at $499 and people were entranced by this elevation. If I'd like to save 500 piece. But how is this even possible, especially when nobody even knew about the effect?
