Suppose that you are a buyer. your buyer value is $30 and you buy a book for $40. what is your gain or loss?

The buyer value is a concept that is more important to the customers. This refers to the amount that the buyers are expecting out of the purchase of some goods. If I bought a book at a price of $40 then, I loss $10 in the process because as a buyer I expect to pay only $30.
