I was not at home during delivery and there was no delivery slip?

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.
