|This will show how much money a shopkeeper will be willing to pay for a given item in your inventory. Different shopkeepers may give you a different price for the same item, depending on their disposition; in addition, other factors, such as how many similar items the shop already has for sale, or any damage on the object, may lower the price they will be willing to pay.|
At the moneychanger's, this command functions differently. See exchange for more. It also works slightly differently at the repair smith.
