difference between priority mail and express

difference between priority mail and express is crucial for customers choosing USPS shipping options. Priority Mail is a faster, more affordable option for domestic shipments, typically taking 1-3 business days to reach the destination. It includes tracking and delivery updates but does not offer a money-back guarantee. Priority Mail Express, on the other hand, guarantees overnight delivery by 3 PM the next business day in most areas, making it the fastest USPS service for urgent shipments. While Priority Mail is more affordable, Express Mail offers a higher level of reliability and speed.
