The USPS 5-7 delivery shipping option refers to a service provided by the United States Postal Service (USPS) where packages are expected to be delivered within a timeframe of 5 to 7 business days. This option typically offers a balance between cost-effectiveness and reasonable delivery speed, making it suitable for non-urgent shipments where timely delivery is not critical. It's often chosen for items that are not time-sensitive or for customers seeking a more economical shipping alternative.
