Package delivery is the process of transporting goods from one location to another, typically from a seller to a buyer. This service is commonly used in e-commerce, where customers order products online and have them shipped directly to their homes. Delivery can be handled by various companies, including UPS, FedEx, and USPS, which offer different shipping options based on speed and cost. The delivery process usually involves several steps: the package is prepared for shipment, picked up by a delivery service, and then transported to a distribution center. From there, it is sorted and sent to the final destination. Customers can often track their packages using online tools provided by the delivery service.
