So the prcie that the firm charges the price that the customer is willing to pay. This is very common in markets the seller present a number of products and quotes a higher price and then have a healthy conversation with you and then agrees the price. Some people agree at the spot and some agree by heavy debate and forces the seller to reduce the cost otherwise the customer is going away. So this means the company is charging reservation price, takes all the consumer surplus from consumer and captures the social gain which is the maximum gain possible to extract from the person.
