ground advantage vs first class

ground advantage vs first class Ground Advantage and First-Class Mail are both shipping services offered by USPS, but they have key differences. Ground Advantage is a more economical service for heavier packages and takes longer to arrive compared to First-Class Mail, which is faster and ideal for lighter items (up to 13 ounces). Ground Advantage may be used for bulky items, while First-Class is best for letters, small parcels, and documents. First-Class Mail is generally quicker and more expensive than Ground Advantage, but Ground Advantage offers a lower cost alternative for heavier shipments that don’t require urgent delivery.
