Compare USPS Priority Mail to Priority Mail Express
U.S. Postal Service Priority Mail and Priority Express Mail both get your items to their destination fast, and they both offer features like tracking numbers and a standard level of insurance. The main differences between the two are delivery times and dates. Priority Mail Express gets your letters and packages there faster and can deliver seven days a week, but you'll pay extra for those services. The other important difference is that Priority Mail Express is a guaranteed service.
