How to Get the Best USPS Rates
Always use commercial pricing — platforms like atoship give you commercial rates on every label at no extra cost
Use Ground Advantage for non-urgent shipments — saves 25-40% over Priority Mail
Use Flat Rate boxes for heavy items — a 15 lb item in a medium flat rate box costs $14.32 vs $40+ weight-based
Schedule free USPS pickup — save time by having your carrier pick up packages from your door
Compare with UPS and FedEx — for packages over 5 lbs, UPS/FedEx Ground is sometimes cheaper than USPS
