Express deliveries refer to a shipping service that prioritizes speed, ensuring that packages reach their destination quickly, often within one to two days. This service is commonly used for urgent items, such as documents, gifts, or medical supplies, where time is critical. Companies like FedEx and UPS offer express delivery options to meet customer needs. These deliveries typically involve a higher cost compared to standard shipping due to the expedited handling and transportation processes. Many express delivery services provide tracking options, allowing customers to monitor their package's journey in real-time, enhancing convenience and reliability.
