The Grand Exchange Collection Box is the box used to collect items/money that a player has purchased/sold from the Grand Exchange from any bank in the game. To access the collection box, players must right click a banker and select 'view collection box' and select the item they wish to withdraw. It is impossible to create or abort an offer via the collection box. This can only be done at the Grand Exchange itself. To alert players that one of their Grand Exchange offers has been completed, a message will be given: e.g. "Grand Exchange: Finished selling: 2x Tuna".
Like when accessing a bank or the Grand Exchange, players must enter their bank pin to view the collection box.
