Our contention is not to invent the miracle method that you would never deceive you in purchasing or becoming better negotiators, but to analyze the selling methods that you know what you will say a commercial or when a seller wants to sell you a product. Because what is a purchase that is instinct or actually planned and anticipated? This is a temporary relation to very high levels of involvement between you and a seller. And in recent years consumers have become very demanding, because they have the opportunity to learn and especially to compare both prices and features of products or services, and to have opportunities to achieve a sale needs to be structured and therefore your intention to purchase becomes at the same time.
