Trader tokens. A cart mechanic and a bargain mechanic

[YegoRomka]

Hi!

As gamemaster I want to provide an advanced trading for my players with a cart mechanic and a bargain mechanic.

It would be great if instead of buying an item directly, the player could add the item to their cart, creating a shopping list and seeing its final price.

It would also be great to give the ability to bargain. When a player buys an item directly, or creates a shopping cart and then, instead of buying it, by clicking on a separate button, they create a request to the gamemaster and indicate the price for which they want to buy or sell the items. Now, when my players want to bargain, I have to refund them for their purchases manually.

I would be very grateful (including financial support) if you could add these two mechanics to your module.
Thank's!
