When will my Good 'Til Cancelled listings be required to include dispatch time?
You have until 31 October, 2009 to update your Good 'Til Cancelled (GTC) listings with your dispatch time. However, we encourage sellers to start updating these fields as soon as possible on their Good 'Til Cancelled listings. You already need to specify these fields on new listings and relistings for most other listing formats.
Yes, the bulk editing tools are available now. You can edit these fields using the Bulk Edit tool in My eBay, Turbo Lister and third party tools.
Sellers with Good 'Til Cancelled listings created before June 2009 may need to update those listings with a Return Policy
Casual sellers are currently required to have a returns policy (a return policy of “No returns accepted” is also valid). Business sellers are legally required to accept returns. However, some Good Til Cancelled listings created prior to June 2009 do not have a returns policy specified. These listings will need to be updated with a returns policy by 31 October. A return policy can be updated using the same tools and procedures as when updating dispatch time.
After 31 October, listings that are missing a dispatch time or return policy will end instead of automatically relisting. Ended listings will be displayed with “eBay note: Listing ended - Needs additional information” in My eBay. You will need to update the dispatch time or returns policy before you can relist.
Which of my listings need to be updated?
Listings in the Property, Local Services and Motor Vehicle categories are exempt for both dispatch time and return policy requirements as well as listings in Classified Ad format. Listings where "Local pick up" is the only shipping option do not require a dispatch time but may still require a return policy.
Listings that have ended because they were missing dispatch time or return policy will be displayed with the following image:
