Gamebreaking, Limitless Limited Supply Items (Patreon)

I have received a credible report that upon logging in for the first time Dealer Jadyan in Netherstorm is allowing the sale of limited supply items he would not otherwise. Th items he sells all have significant mark-ups of over 1000-3000 gold on the AH. This is almost as good as a dupe if valid.

It is 3:21 am here and I must sleep so I cannot test this personally.

EDIT: The Patreons in the comments below seem to have tested this  more comprehensively than I or any single individual could. To summarize, it is a valid play but somewhat erratic and requires periodic resets. I greatly appreciate the help of Patreons on this.
