GIN means Get It Now which a seller can set at a certain amount & if a bidder wants it, they can use that option without having to wait till the auction ends. You cannot add that option yet because you don't have your "Seller's Wings" badge yet. Once you get that, then you can start adding the GIN to your auctions. But keep in mind, that with the GIN option, you don't get all of the credits because Listia takes a cut of it!!
