Your terms are contradictory. One place it says the auction will end at a given time unless buy it now is used. In another place you say you will end it at will. Sounds pretty flaky to me, but that is typical of ebay auctions.

I was watching an auction on a Ferrari the other day, the price was too good to be true, car located 15 miles from me. The entire auction vanished without a trace within a couple hours of its ending time. Flaky.

I marked your auction and will watch it, any disappearing acts up your sleeve?

OOPS, I see it closed already, congrats.
