"how i can delete my listing in bulk

Good Evening @Seller_aQBc1v5JRs1jf,

If you are no longer going to be listing a particular ASIN on the platform, ensure you delete both your offers and item data contributions. You can do this by entering an "x" in the add-delete field in your Inventory Loader file. This will completely remove all data associated with your SKU.

Please let us know if you have questions about this process or you may reach out to Selling Partner Support at anytime.

Sincerely, Cooper_Amazon
