Auctions can only be edited if no bids have been placed. If there are bids but the reserve price hasn’t been met, you can lower the reserve price to within 1 cent of the current bid.
To edit your listing go to My account, click on Items I am selling and locate the appropriate listing. Then click the Edit button.
Alternatively you can open the listing and click the edit buttons that display at the top of the listing to make changes.
