If you have stock in multiple locations or you’re using international distribution partners, you can add additional shipping origins from the Physical Goods section of your Profile page:
You can manage inventory, assign fulfillment partners, and configure separate shipping rates for each individual shipping origin. When your fans buy your merch, we’ll automatically pick stock from the origin that offers them the cheapest shipping based on their location and your available stock. Because sales tax is calculated based on both buyer and seller location, it's important to make sure your shipping origins are set up correctly.
