what’s the difference between priority mail and express mail

what’s the difference between priority mail and express mail refers to the distinction between two shipping services provided by USPS. Priority Mail is a reliable and affordable service that guarantees delivery within 1-3 business days, depending on the destination. It is ideal for regular shipping needs and includes features like tracking and delivery confirmation. Express Mail, on the other hand, is the fastest service offered by USPS, guaranteeing overnight delivery to most locations, even on weekends. It also includes features like tracking, insurance, and delivery confirmation but is more expensive due to its expedited nature.
