If you’re using the built-in Printify shipping rates (default option)

All you need to do is assign a new shipping profile to the product for which shipping costs were changed and republish it. 

1. Navigate to the My Products section in Printify and click on the product card.
2. Click Edit under Assign shipping profile and select the “Automatically assign a new shipping profile” option from the drop-down menu.
3. Click Publish to sync the changes with your store.

If you made any changes to your products from the Etsy side, make sure that only the Shipping profile box is checked when updating the shipping rates. That way you will not overwrite the other product details.

If an existing profile with matching settings has already been created (for example, if a product was previously set up using Bella+Canvas 3001), the same shipping profile will be automatically reused for all subsequent Bella+Canvas 3001 products with the same Print Provider.

If you have custom shipping rates set up with Etsy

1. Navigate to your Shop Manager in Etsy and choose Listings.
2. Choose the product that you want to edit and click on the gear icon → Edit.
3. Scroll down to the shipping section of the listing and click Edit next to the current shipping profile of the product.
4. Make the necessary changes and click Save profile, followed by Publish.
