Items purchased successfully should be taken out in-game by the "Trade Caravan Master". There are three locations in the game: Chang'an (433, 182), Chang'an (271, 45), and Jianye Yamen (8, 12). It takes about 15 minutes to get the number, and you must use the character you bought the number from to get it out; there is no way to get it out from another character under the same pass. Once you find the "Trade Caravan Master", click on the character you want to trade, then click on the character you bought to take it out~~
