<Right Click> on inbox items to loot the gold, loot the item and destroy the letter, in that order, if any.
<Right Click> or <Left Drag> to add inventory items to the attachments.
<Right Click> to add inventory items to the trade frame.
Note that due to limitations of the 1.12 API, behind the scenes, the items must be sent in separate mails.
As a result of this COD will only apply to the first item if multiple items are added.
Also note that COD is always ignored when opening, both automatically as well as by <Right Click>.
