Express delivery is a shipping service that ensures packages are delivered quickly, often within one to two days. This service is popular for urgent shipments, allowing businesses and individuals to send items faster than standard delivery options. Companies like FedEx, UPS, and DHL offer express delivery services, which may include tracking features for added convenience. The cost of express delivery is typically higher than regular shipping due to the speed and efficiency involved. Factors such as distance, package weight, and delivery location can influence the price. Many online retailers provide express delivery options at checkout to meet customer demands for rapid service.
