Your right, it doesn't and it was worth a fair shot. However, I don't make the rules and even if I did would still say that everyone deserves a fair chance at bidding on it. If you are that interested in it (which I am glad for) then bid whatever you feel is a fair number and see how it plays out!
I am sorry but I can not do that. Once someone has made a bid on the auction you can not go back and change the specs of the listing. Everyone deserves a fair chance. That is a really good bid amount for this item, if you are that interested bid what you feel comfortable and then wait to see what happens!! Sorry, good luck and happy bidding!
