Alternative Tools

• USPS Mobile App: Rate calculator built in

• Third-party shipping software: Pirate Ship, Shippo, Easyship — often discounted commercial pricing

Key Variables Affecting Price

• Weight: Primary driver for packages
• Dimensions: Dimensional weight pricing for large/light packages
• Service speed: 7-21 days (First-Class) vs 6-10 (Priority) vs 3-5 (Express)
• Tracking/Insurance: Included in Priority/Express; add-on for First-Class

Pro Tips

• Use Forever International stamps ($1.65) for 1 oz letters — valid despite rate increases
• Consolidate items into one Priority Mail box vs. multiple First-Class — often cheaper
• Japan Post delivers reliably — no need for premium service unless time-critical
• Declare value accurately — customs delays hurt more than duty savings
