Quick answer
Nordstrom Rack no longer ships outside the United States, including Canada. Its FAQ says shoppers in Canada can order with US billing and shipping addresses. Nordstrom.com has different rules.
Before ordering
A policy accepting a US address does not automatically confirm freight forwarding services. Obtain confirmation of any separate arrangement before ordering and check the item’s return terms.
Compare the full cost
Compare the same product and quantity, then add the charges actually shown for the order. Distinguish prepaid charges from any amounts still payable by you. Keep the confirmation and applicable terms.
