Hey guess what? You can also order your store listings in your basic "my ebay" by quantity. I just checked it out.

On my "My Ebay" page I have it set up to show sold items and then under that is the list of current listings. I have it in "time ending soonest" order, but you can click on that and change the sort order to "available quantity highest" or "available quantity lowest".

So just go into your usual "My ebay" view and change the order there and you will see the zero quantity listings.
