How to Save on 2025 USPS Rates

Commercial pricing can save you up to 89% compared to retail rates. AtoShip provides access to the deepest USPS discounts without any monthly fees or volume requirements.

3. Leverage Regional Rate Boxes

USPS Regional Rate boxes offer flat-rate pricing based on zones, which can be cheaper than standard Priority Mail for heavier packages shipping shorter distances.

4. Use Free USPS Supplies
