A mob that is a shop-keeper when hired will make their way to your
shop storeroom if you have one, if not to your treasury. A shopkeeper
will often have a speciality type that they will purchase on your behalf.
This they will tell you when you ask them about themselves before hiring
them. In order for them to be able to purchase the type of item they can
buy you need to leave coins on the floor of your shop storeroom and they
will buy what they know until the coins run out. The items that the
shop-keeper buys are put into your shop storeroom. They can be sold if
you do not remove them from there. A shopkeeper will buy a maximum of 5
of a given item. You will make a profit on their sale as a general rule.
The shop-keeper keeps half of the sale proceeds and puts the other half
on the floor of your shop storeroom.
Smiths will cost you the normal amount of money to repair your armour
and weapons but they will put some of the coin they take from you back
into your shop storeroom or treasury. If they are accessable by other
PC's they will give you a percentage of the earnings they make on
repairing items.
