29.13 The sale-value command.

SALEVALUE is a useful command which determines the price a shop will attempt to sell an item at. It does not govern the price a merchant or shop will purchase it; they have their own means of assessing value. You can set the salevalue on commodities and personal items. Value changes are logged in a shop's actions log which can be viewed in the shop's stock room by typing SHOPACTIONS.

You will only be able to use SALEVALUE if you are a ranking guildmember of the guild owner of a shop, or a ranking government representative of the city owner of a shop; or if the shop is owned by an individual then you must be the owner him/herself or have been FRIENDed to a value of 90 or above by the owner. See HELP FRIENDS for details how to declae friends and enemies.
