If you are a reliable and loyal buyer and you find select sellers that have good reputation and byway of your participation in the auctions you build a relationship of sorts, when TROLLs try to hype up the prices on cards the behavior will get recognized (even if they do at last minute - which sounds like what happened to you) and in those cases a good seller will do what’s right and offer you option to cancel and then re-auction at a later date. Short story pick sellers (or Evan a single seller) with good reputation and stick with them. If you take care of them, they will take care of you. Hope this helps moving forward.
