You can't download the ended listing but you can always copy/paste the info

I have one TL listing that is a template - has all the basic info that I include in all my listings. Then I just duplicate that lisiting so all I need to add is the specific item info and the photos.
TL is free. You create listings in TL and upload them to Ebay when you are ready. It really helps me when I have the info for the item but not the photo (or vice versa) and when I want to get a head start on listings for the holidays.
There are other programs/websites you can use (some free, others not) but I have been using TL for so long that I cannot make head or tails of the others
