ground delivery means refers to a shipping method where packages are transported over land, typically using trucks or vans, rather than air. Ground delivery is often used for shipments that do not require expedited delivery and can take longer to arrive than air services. Ground shipping is generally more economical compared to air shipping, especially for heavier and larger packages. Ground delivery services are offered by major carriers such as UPS, FedEx, and USPS, and are suitable for domestic and regional deliveries.
