Practical Tips for Saving on Flat Rate Shipping
- Print Postage Online: Using USPS.com or reputable shipping services often results in lower rates than retail.

- Check Alternatives: For lightweight or short-trip items, compare First-Class and zone-based rates for potentially better prices.
- Military Shipments: Use the APO/FPO/DPO Large Flat Rate box for discounted shipping to military and diplomatic destinations.
Best Practices for Using USPS Flat Rate Boxes
- Proper Packing: Use bubble wrap, packing peanuts, or crumpled paper to cushion your items. Well-packed boxes protect your goods and help meet USPS mailing standards.
- Label Clearly: Double-check addresses and print legibly to avoid delivery issues.
- Seal Securely: Use the package’s built-in adhesive. Avoid using extra tape to overstuff boxes—USPS may reject overpacked shipments.
- Timing: Ship early during holidays as Priority Mail can still experience delays during peak seasons.
Cost-Saving Tips When Shipping To or From Different Locations
- For long-distance shipping (coast-to-coast), Flat Rate boxes usually provide the best value, especially for heavy items.
- For local or regional shipments, compare standard Priority Mail rates (which depend on distance and weight)—these can be cheaper for lighter items.
- Sending gifts or care packages to military addresses? The APO/FPO/DPO Large Flat Rate box offers discounted military pricing.
- International Flat Rate Boxes are available but follow different pricing; check with your local USPS branch for details.
What If Flat Rate Isn’t the Cheapest Option?
USPS Flat Rate is best for heavy shipments traveling far. But if you’re sending a light package or within the same state, always:
- Weigh your package
- Check the cost of standard Priority Mail or First-Class Package
- Compare to Flat Rate
Choose the most cost-effective option before you ship!
