I was thinking it would be cool to have a feature where you can sell items from your inventory, but instead of selling back to the game, you could sell directly to players that collect that specific item.
Like, people opt into being a collector of, say, pee snowballs or red staplers, and sets the highest price they would pay for a single piece of that item (maybe expires after a week to make sure only active players are listed). Then from the inventory, people would offer the item to the collectors.
Or collectors can have like a little collectors bank that gets money taken from it when people sell an item to them at the price they want.
idk, that's the system i just thought of. I would just like to sell some items directly to collectors instead of leaving them in my merchant.
