How do you sell some thing to some body?

I will listen and understand what the customer is in need of and give the best description of the product and reason as to why they should buy it 

First we have to know that what the consumer wants and which tip of product consumer wants and than we will show the product benefits and then we will sale to the customer....

"Sale" means "Serve". If you want to serve someone, you need to understand his/her needs. The more information about customer's needs drive you to a better "Serve" which will help you to sell.

By describing the product features to the buyer and marketed better through product-specific marketing items
