[Suggestion] Implement automatic trade straight from the website (Auction House Style)

If I list an item from my premium Tab I would love for it to be sold and sent automatically to the buyer (like world of warcraft or ff14), same if I want to buy something from the website, I should just receive the item thought "mail" and get the price deducted from my currency tab, without needing to whisp multiple "asian" accounts that never reply, this strongly reduces the whole "setters" problem and would, imo, be way healthier for the games economy.
