Hmm that seems excessive, the hedging fee is no way near that amount so I am unsure as to what may have happened in this instance. I would advise you to contact SR support on the main site and open a ticket outlining your situation. By the way the vendor doesn't get the benefit from hedging if the value of BTC goes up either, just the dollar amount of the listing. Just a thought, did you order have some sort of expensive shipping option?
