Lets say you are using ServerRewards or GUIShop or whatever economy plugin instead of the money balance being linked to the steamid of the player it is a physical item (something you can edit the stack size for with StackSizeController) so you can have like money bags in your inventory? And when it is in your inventory it can be used to spend in those shopes.

Does that exist?

ah yeah thats smart indeed thanks alot

yes I use it instead of economic using my own menu with skin money, and it works great, players have to carry money to buy things from Guishop or SR, you need to adjust sr or guishop to make it possible
