An address change on an order going abroad warns you about import duties first

When you change the shipping address on an order that ships to another country, Tacey now tells you before you save that Shopify may add or change import duties and tax on the whole order. That can leave a balance to pay or a refund owed. A domestic order shows nothing. Tacey never charges or refunds anything for it, and it shows you the exact new amount right after the change so you can settle it in Shopify.
