I replied to a post about this auction just yesterday on Facebook!
I noted that this auction does allow bidding by the auctioneer and/or their employees...you're not competing just against other bidders. Most cards show the same "user" as the high bidder, at prices that could be considered beyond their fair value. I do like some of the cards and would be a bidder if it weren't for these red flags and seemingly overinflated bids.
