Sales skill
First understand the customer's needs and see if the customer's eyes are fixed on high-end machines, mid-range machines or low-end machines. If a customer comes to the store and takes a fancy to the high-end machine at a glance, you don't have to explain the low-end machine to him. Try to say more compliments to make the customer sound comfortable (but don't flatter too much). High-end machines emphasize identity, mid-end machines emphasize performance, and low-end machines emphasize practicality, high quality and low price. In this way, all kinds of needs can give customers a positive answer, but remember, if you start to look at customers with mid-range models, you'd better recommend low-end practical models, because everyone has vanity and what he sees is not necessarily what he wants.
