So I don't think you can do a Gin if there are bids on an item???..... you might check with listia, but you might be able to accept an offer from a bidder??? And if that is the case I would like to have an opportunity to offer on it too ;-)
I'm not sure, I think you would have to check with listia to see what their rules are, there is a link at the bottom of the page that will take you to an area where you can post questions to the listia board, they usually answer with in 24 hours
