GIN is "get it now". It means the person doesn't have to wait for the item that they're auctioning on. No bids. An automatic price. It's whatever you - the seller - want the price to be for the item that you're selling. If someone clicks GIN, they get that item automatically, no other people can bid on it. (If they have enough credits, of course.) When you put your item up for bid, the summary of it wil have an option for GIN. Not sure if you can change it to GIN if someone already placed a bid on that item, though. Hope that helps!! :D
