There is an option for the seller to cancel until the minimum has been bid. That option then disappears from the seller's menu. That is not explained in the rules but that is the way it works. Here are the rules.
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.
