turns out I cant do GIN yet anyways, I do not have seller wings, Im new to lista so I need to get 5 positive feed backs and five auctions or something like that in order to unlock the GIN for me. I'm sorry that I can't do it yet. But I will be selling more soon.
I can not put a GIN it when its already been put up, I don't believe i can change it. However I have more items to put up on lista including another copy of this Movie, I will make sure to add a GIN on that one when I put it up.
