a Get it Now price. No one has bid yet, so it's still possible to add one. I would offer you 5,000 credits if you would accept and add the GIN to your auction.
I see you added it to the description part of your listing. There should also be a place in the bidding section to add a GIN. I can't buy it for 5,000 credits until I can click on the GIN button. It's kindof like a buy it now on ebay.
