This article explains how to cancel or lower the price of items you’ve listed for sale.
To cancel a listing, navigate to the item and click Edit listing at the top of the page.
An Edit listing window will appear. Click Cancel all listings.
Canceling listings requires a gas fee to make the listing unfulfillable by other users. Review and confirm the cancellation in your wallet.
If you can’t access your account, you may be able to use a third-party service such as revoke.cash to remove the ability for the listing to be filled on OpenSea. Please be aware that if you use a third-party service and you grant approval to OpenSea at some point in the future, listings that aren’t expired or canceled may be able to be filled again. OpenSea does not make any guarantees about third-party services.
Lowering the price of listings
You can lower the price of a fixed-price listing by navigating to your item and clicking Edit listing at the top right of the page. You can only lower fixed-price listings on ERC-721 NFTs, not ERC-1155s.
Enter the new price in the Set new price section and click Continue. You'll need to review and confirm the listing in your wallet.
