So you want items in shop/markets to have no numbers on icons? I guess its imposible because it represends a number of items in stock and its made for it - making it clear, when given item can be bought and how many of copies are able to be sold.
However, you can use triggers here.
Instead of selling items by shop, and to that market abilities (no target) with Player Property conditions (gold/lumber).
If player has enough of them, create given item and give it to player.
Remember to check if he has enough space - because in wac3 ladder items dont drop on ground if equipment is full.
