what is the difference between ground advantage and priority mail

what is the difference between ground advantage and priority mail refers to the comparison between two distinct shipping services offered by USPS. Ground Advantage is a more affordable shipping option with a longer delivery window, typically 2-8 business days, depending on the destination. It is suitable for heavier or larger packages. In contrast, Priority Mail is a faster, premium service that offers delivery within 1-3 business days. Priority Mail includes additional benefits such as tracking, delivery confirmation, and insurance for certain items, making it ideal for shipments that need to arrive more quickly.
