Ground shipping is a form of shipping that involves parcels being sent by road or rail. It is the most cost-effective mode of transportation for shipping packages and is the most common and standard mode for domestic transit. Ground shipping is generally forwarded through freight services such as FedEx and UPS, which route smaller and larger trucks across the country to ship and deliver products. Ground shipments are slower than air shipments because freight trucks stop at various distribution centers across the country to drop off and pick up multiple shipments. Ground shipping is a great option for sending packages domestically, and it is the most affordable option for domestic shipping. Ground shipping is also useful for the last-mile delivery of imported goods. Ground-based shipping is more economical when the destination address is in the same state or nearby. Ground shipping is a good option for online sellers who want to offer fast, 2-day shipping at a low cost, which provides a premium shipping option.
