I can't make any changes once anyone has made a bid on it. Therefore, Listia won't let me add a GIN now. You can take a chance that someone will outbid your 2000 bid AND I can set you up another one just for you with a 2000 GIN on it and let you know when that has been completed. So sorry, most people don't know that the seller can't change something once a bid has been place on the item. Listia does allow the seller to add an UPDATE to the wording but it goes on the bottom of the listing - It's might be that no one will outbid you...one good thing - another good thing...is that I'll be listing another one right after this one has been sold. So sorry.
