Hmmm, I'm not absolutely sure. However, I made a huge mistake last night while listing a new item. The new item was similar to an item that I'd already listed, but instead of copying the listing, I hit the edit button instead. Shortly after, I was very surprised (and excited) to see the rapid response to the new listing....... until I realized my mistake. The new item had taken on the stats from the older listing. Living and learning :)
