what does next day shipping mean refers to a delivery service where the shipping carrier ensures that a package is delivered to the recipient the next business day after it is shipped. This is a premium shipping option offered by major carriers like UPS, FedEx, and USPS. Next-day shipping is typically used for urgent or time-sensitive deliveries and comes at a higher cost compared to standard shipping options. Next-day shipping can apply to both domestic and international orders, depending on the destination and the service selected by the customer.
