How do I remove a product from the Amazon feed? – Pulse Commerce Help Center

Go to Products > Product Catalog Manager.
Click the Edit link beside the product which you will be removing from Amazon.
In the Product Editor, click the Advanced tab.
In the Edit Custom Product Attribute section, select Amazon Active attribute and set the value to 0.
Update the Amazon Active row.
The product is now telling the system that it is no longer an Amazon Active SKU, and Pulse Commerce will no longer push data for this SKU to Amazon. If you wish to remove the product from Amazon listings completely, continue to the next step.
In your Amazon Seller Central account, mark the product as out of stock. The easiest way to do so is to mark the inventory to 0. You can delete the product in Amazon, or keep the product with 0 inventory.
