I am sorry, but I don't do GIN's with y auctions. I wouldn't know what amount to set for a GIN anyway. I wish you luck if you decide to bid on this auction.
Your last bid was for 10 credits. But someone has bid more. They never show the exact amount that the last person bid. If you look On the right, you will see Bid History. Under that it shows the high bidder. And under that is a square with the words, Bid History. If you click on that square it will show all the bids for the item. Good Luck!!
It never shows how much the highest bidder bid until someone goes over that amount. It's a bit confusing and took me awhile to catch on to how the bidding works.
