- Prohibited Items: USPS has strict guidelines about what you can and cannot ship—especially to military or international destinations.

Cost-Saving Tips for USPS Large Flat Rate Box Shipping
Want to keep your shipping expenses in check? Even with flat rate shipping, there are a few clever strategies to ensure you’re getting the best value:
1. Use the Right Box for the Job
- Tip: If your item weighs less than 6–8 lbs or is smaller than the large flat rate box, compare flat rate pricing to standard Priority Mail by weight/distance—it can sometimes be cheaper!
- Bulk or Heavy Items: The large flat rate really shines for shipping dense or multiple items.
2. Ship to APO/FPO/DPO Addresses
- Discounted Rate: Large Flat Rate Boxes sent to military addresses ship at a slightly reduced price—perfect for overseas care packages.
3. Print Postage Online
- Online Savings: Some online shipping tools offer small discounts compared to post office pricing. Printing at home can save you both time and a bit of money.
4. Reuse Packing Materials
- Boxes are Free: But you can reuse bubble wrap, foam, and other fillers to protect your shipment at no extra cost.
5. Volume Discounts for Businesses
- Commercial Pricing: High-volume shippers (such as e-commerce sellers) may qualify for commercial rates—ask USPS about available programs.
Practical Advice for Smooth Flat Rate Shipping
- Double-Check Contents: Make sure you’re not shipping anything prohibited—liquids, perishable items, and certain batteries have restrictions.
- Keep it Under 70 lbs: Avoid delays or surcharges—never exceed the weight limit.
- Secure Packing: The box must close normally—no bulging or forcing it shut.
- Track Your Package: Use the included tracking for peace of mind.
