overnight mail rates

overnight mail rates Overnight mail rates are determined by the weight, size, and destination of the package. For USPS, the cost of overnight services such as Priority Mail Express is set based on these factors, with a fixed price for packages up to 70 pounds. Other carriers like FedEx and UPS also offer overnight services, which are generally priced higher based on the urgency and delivery location. When calculating the cost of overnight shipping, it’s essential to compare the rates between carriers and services to find the best deal for time-sensitive shipments.
