We had a bad experience with another auction board http://www.nishikigoi.com/.
Our first auction winner went fine and we were more than pleased with the fish at the price we won at. The second time around not so good. We were the high bidder when the auction ended but somehow someone was allowed to come in an hour later and make a bid that was $100 over our bid. When we called the next day they said there was a glitch on the website that night an the late bid was allowed. We felt the fish should have been awarded to us and explain the website glitch to the late bidder. The refused to do that and awarded the fish to the late bidder even though they admitted the problem was on their end. These people also sell a lot fish and have a great reputation but for $100 profit that put aside their integrity.
Now this to is a reputable company so I guess things just happen sometimes on the auctions and the companies seem to always take the position which is best for their profits.
So auction bidders beware!!
