You can usually make changes to your eBay listings, but there are some restrictions depending on what you want to change and when. There’s no fee to revise a listing unless you add a special feature.
You can also revise single/multiple listings in Seller hub, here’s how:
Go to your “Manage active listings” in Seller Hub.
Check the box beside each listing you want to make a change to.
Select “Edit” drop down to make your changes.
