Oh. It was confusing the first time I did it too. You have to put your password in, then I have to put mine in again to confirm it in case you put any items or gold in it. Then it's done but it doesn't really tell you. However if you check the trade page, it shows all trades & will show your Completed Trades when you scroll down & your stuff will be in your inventory.
Lol, I actually have that one in black. That reminds me to change up my House. I have some mermaid-y stuff for it but of course can't afford the bed or window cause the prices are sky-high and that's when it's even available in the MP, which is very seldom. But thanks for reminding me to set up what I have so far. mrgreen
