if i buy a store, which has 20 items slots, can i then in theory buy 20 shop pad keepers and place there and get 20*20 = 400 items slots? or are there restrictions to how many shop pad keepers you can place there? if i can add more item slots by simply adding more shop pad keepers there will be little point in bidding for more than one shop... or?
A shopkeeper pad takes up 6 item points, so you can in theory add 3 shopkeepers and then you have 2 points left for signs or items. http://www.entropedia.info/Info.aspx?chart=MiscTool&name=Shopkeeper_Pad
Signs use 1 point, screens and displays use more. If you have a static image or text, a sign is fine, else you need a screen. - Deathifier
