USPS Priority Mail typically takes 1 to 3 business days to be delivered domestically. Delivery speed depends on the distance between the origin and destination, and there is no official guaranteed delivery date for Priority Mail. It includes free tracking and up to $100 insurance for most shipments. Saturday delivery is included at no extra cost, but there is no delivery on Sundays. For faster guaranteed delivery, USPS offers Priority Mail Express, which delivers overnight or within 1-2 days with a money-back guarantee.
