What selling point would you use if you were to sell our product service to our potential customers?

To enable for me to sell products, first and foremost, i have to be knowledgeable on the product that I am selling. Then, establishing rapport to my costumers is a key to gain trust because once a person is trusting you then its not difficult to interact or communicate. I have to know what kind of person I am dealing with and focus on what they need so that I can have basis of what I have to offer.
