Joe D.Money Order stop takes forever by the Post Office.
Its a tough situation... and I can't see any great answer.
If the seller has patience (and believes you), you could both wait it out.
Or if you trust the seller enough, send a check. If the original money order makes it to the seller, you chance that he would keep both payments. But if you trust him to refund one of the payments... maybe that is your best bet.
I will say... those postcards are nice! Great item. Hope it gets resolved and you get your card soon.
