You can ask for a refund at USPS.com if your Priority Mail Express mailpiece is not delivered within the promised window of time. The Post Office will no longer process refunds there.
If the parcel is not delivered by the promised certain delivery date and time at the time of shipping, USPS® will reimburse you again for postage and, if you purchased it, the Sunday or holiday premium cost.
There is a money-back guarantee on all Priority Mail Express shipments from USPS. Within two days and so by 6:00 pm local time, these packages must reach the recipient's address. If your product isn't delivered by the Scheduled Delivery Date listed on the label, you can request a postage refund.
