The postal service will try to deliver the shipment to an authorized person in your household. If nobody is at home they will leave a note, asking you to pickup the shipment from the post office. It is your duty to do that within 2 weeks, otherwise they will return the shipment to the sender. We may reship your order once at no cost but you cannot claim a full refund if reshipment + delivery fails once more. Avoid all the issues by checking the online tracking info as it will show the delivery attempt there, then collect the shipment in time.
