[quote=Lostnomad1]so after an auction ends another one starts if it has 250 available?

Maybe. Some of the bidders may be bidding on more than one quantity. If 25 people each bid and won ten items each, there would be none left for a new auction (presuming CBid had no more to auction). Usually there are new auctions of the same things a short time (hours, days weeks, centuries) after the auction closes.
Remember, losing an auction is a sign of weakness and we are all watching.
I hear that once you get Platinum membership status, you get a weekly report of the worst losers so you can ridicule them and bet against them aggressively in the auctions.
