If you have a piece up for auction, it's still yours until somebody wins it. I don't see any reason why someone couldn't cancel an auction without explanation before the reserve is met. After the reserve is met, I would frown upon this, although at the end of the day I doubt there is anything either a bidder or Audiogon could do about it.
Can you cancel an auction?
I was just wondering whether it is normal or allowed to cancel an auction before it is over. I don't want to do it myself, but I was recently following an item (hadn't actually bid on it, but was curious as to what it would fetch), and then it just up and disappeared several days prior to ending. I looked through the auction rules but didn't find any answers, and I don't have much auction experience on ebay or whatever. Any comments as to the rules or etiquette of doing this? I'm not upset at all, just curious.
