How can we assimilate costumers with our unique explanation?

We should have strong presentations and explaining any little by little details to costumers about our products. We should be friends with costumers and listen to their expectation of their purchases and try to help them to find out details which related to what they want and show them all proper ideas about their shopping box and get them too much information about their offers,”who knows ,some people love offers to buy more products “ It’s completely related to sellers to have creative ideas about selling more products. I think it’s work ,therefore we should get more information everyday about the basic and the details about products those we are working on.
