Since there's been some confusion.
Day = Round.
We call them ROUND often because they technically last for three days. The Rounds/Days are closing in order. Last night at midnight round/day 3 closed. Tonight at midnight round/day 4 will close.
If you don't know which round/day is about to close, simply click on the posts. If they say, for instance, "Day 3, Item 1" and at the bottom of the comments there's a notice along the lines of "THE BIDDING IS CLOSED" then round/day 3 is closed.
We're sorry for any confusion. This auction has been a new experience for us, and is very much learn-as-you-go.
Thank you, as ever, for your patience.
