Well u can also Make Tickets in the ItemMall and People can buy them and Trade it vs Items, Crones etc like I did on my old BWG Server.
So People can Trade it Ingame and Activate them for Points for the Mall.
As Example :
Player A buys a 500 RP Ticket from ItemMall (500 Points worth).
Player B is selling a Ring for 500 Points.
Player A Trade the 500 RP Ticket for the Ring and Player B got Points.
