Make sure you’ve added your default Shipping Profile rates before creating Product Shipping Profiles for items that must ship separately.
The Shipping Profiles tool must be enabled in order for shipping fees to appear at checkout. Only customers in the areas you set Shipping Profiles for will be able to purchase from your store. (no shipping settings = $0 shipping worldwide)
To Create a Product Shipping Profile:
Log in at my.bigcartel.com.
Go to the Account section.
Under the Shipping Profiles section, click Edit your shipping.
Under Product shipping profiles, click Add product shipping profile.
Click in the Name field to edit the example profile name, and enter a name specific to the product it’s for.
Click + under Shipping rates.
Under Add shipping profile, select a country, region, or zone
Click on each of the default Shipping Methods provided to edit the Name, Description, and rates, or to delete that method entirely.
Click Save.
To create additional Product Shipping Profiles for different regions or zones click Add shipping profile again and walk through the previous steps to create another Product Shipping Profile. To edit an existing Product Shipping Profile, select it from your list of profiles to open it up for editing.
To assign Product Shipping Profiles to a product or product variant:
Head to the Products tab.
Select the item that must ship for the Product Shipping Profile rate
To assign this override rate to the entire product, scroll to the Shipping Profile field and select the new override rate from the dropdown menu.
To only assign this override to a specific variant, scroll to the Variants section. Select the variant you want to edit, and choose the correct Product Shipping Profile from that dropdown menu.
Click Save.
