Unfortunately for you joboy is correct. In your description the first thing you state is: 10 necklaces... so you cannot say "winner gets 2" when someone asks a question. According to Listia rules, the winner will get what is in the description. In this case it means the winner gets ten (10). If you had put, say, "I have ten necklaces.... winner gets choice of two". Then you'd be covered. Description cannot be changed once bids have begun coming in. People are bidding on ten necklaces. We ALL learn the hard way.
You know this is the first auction for this seller and we all need to learn, Maybe it would be nice to give them a learning experience and not chide them for using the wrong "language" in their auction.
