Open Seller Dashboard → Settings → Shipping. Add a delivery option, give it a clear name, select the country or countries it applies to and enter the price. You can create more than one delivery option for the same destination when buyers should be able to choose between services.

You can also use the available quantity, weight, free-delivery, state/county or postcode controls where they are appropriate. Only add destinations you can genuinely serve. At checkout, Light Ideas uses these rules to determine whether each seller can deliver the products in the basket to the buyer’s destination.
