GIN's are a Get It Now feature you can add to your auction after have you Sellers wings. They are an amount you post that allows a bidder to bid the GIN amount and the auction ends right there and then. People that ask for them when you are new don’t know the rules. They never bid anyhow. GIN’s also cost you credits to do them and they have to start at 2000 credits so if no one takes the GIN you have wasted credits.
