Father's Factory ships via the US Postal Service or UPS depending on weight and destination. No P.O. boxes. We aim to ship items within 1-2 days of payment (excluding weekends & public holidays).

If you live in an area experiencing an unexpected service delay (i.e. severe weather, natural disasters, unscheduled events, etc.), please note there may be additional shipping time to receive your order.
