what is ground delivery refers to a shipping method where packages are transported via ground transportation, typically using trucks, rather than air delivery. Ground delivery is commonly used for domestic shipments and is a cost-effective option compared to air shipping. While ground delivery may take longer to reach the destination, it is often more affordable and is ideal for larger or heavier shipments. Major carriers such as UPS, FedEx, and USPS all offer ground shipping options that vary in delivery time, ranging from a few days to a week, depending on the distance and service level.
