Quick answer
ASOS offers Canada as a delivery destination. Options and charges depend on the basket and address. Do not assume free delivery includes import charges.
Before ordering
Select Canada before comparing prices. Check import charges, currency and return terms separately from transport. A promotional threshold does not replace the customs rules applicable to your shipment.
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.
