Shipping options by market
You can set up shipping options for each market that you sell to. A shipping option is a delivery choice that a customer can select at checkout, such as Standard or Express, and each option contains rates that can vary by product and location. You set up and manage shipping options from Markets in your Shopify admin.
When more than one rate in a shipping option applies to a cart, only the single highest matching rate applies at checkout, instead of the rates being added together. This means customers are charged for shipping more accurately, with less risk of overcharging.
Shipping options by market replace the existing shipping profiles and shipping rates configuration in your Shopify admin. This change rolls out gradually, so until your store is upgraded, you continue to set up shipping in shipping profiles. To learn what's changing and what to do when your store is upgraded, refer to upgrading to shipping options by market.
