Nope, you did not do anything wrong. It's just that sometimes some of our members, epsecially those who have not been here long - forget the rules.
I appreciate the way www.davidlawrence.com handles their auctions. They end a lot at a specific time OR 3 MINUTES AFTER THE LAST BID. This prohibits anyone from sniping you in the last nanosecond. If someone outbids you at the last moment, then you have three minutes to raise your bid. Very best regards, collect89
