what’s the difference between priority mail and priority express mail

what’s the difference between priority mail and priority express mail is a frequently asked question when choosing USPS services. Priority Mail provides delivery within 1-3 business days, depending on the destination, and includes tracking and delivery updates. Priority Mail Express, on the other hand, is a premium service that guarantees next-day delivery or 2-day delivery for some locations, often by 10:30 a.m. It also includes tracking and a money-back guarantee if the package is not delivered on time. The main difference is the speed of delivery and the associated cost.
