Give us the option to cancel a COD.
Far to often now the other player has no intension of paying and just wants to grief you by tying up the item in limbo status.
It's bad enough that we don't have an AH in this game without making the only real other option a griefers playground. Make it 24 hours then returned WITH the postage.
That's 3k I just spent on postage to not get the item sold......
Being First is not the prize, it just mean's everyone can stab you in the back.
