In the mail when an item is sold out only the position as coordinates are given. As most players don't know the coordinates of their smartshops it would be better to give the smartshops names.
Like 'Mainshop_floor1_left1' is easy to find for a player, but '123,22,3455' is not.
The coordinates could still be in the mail.
Maybe the area name would be a good idea, also would be easier to handle
than giving every shop a name.
