You should not sell the goods, you should sell all benefit which is contained in the product, do you think it works?

that's where many of us make mistakes, we shouldn't sell the goods to our customers, but instead sell the benefits to the customer. For an example if you were to sell a laptop to a person who only browses and read emails; this person has no use of an i7 processor. The you could offer the client is a dual core or an i3 maximum taking in regards they might want to  multitask at a point. So I totally accept and believe it works cause then the market knows you know exactly what you are selling and they gain confidence in you thus will definitely come back to you or refer their friends who might want to buy a laptop in the future
