3. Under Ship to, choose the Country. The list comes from your markets, with each one’s currency. A sample address is filled in for common countries; every field can be changed.
4. Shipping rate: “Cheapest at checkout”, or one of the options the last calculation offered.

6. Click Calculate price.

• Prices come from Shopify’s own calculation, with your markets, discounts, discount apps, shipping and tax.
• A product that’s out of stock is still priced, with a warning; checkout sells only what’s in stock.
• A code that doesn’t exist is reported as such.
