Packaging Tips
Smart packaging strategies to reduce costs and protect your items
Use the smallest possible box that safely fits your items
Dimensional weight pricing means larger packages cost more, even if they're lighter. Trim excess space to save 20-40% on shipping costs.
Invest in a kitchen scale for accurate weight measurements
Overestimating weight at the counter costs money. A $15 scale can save you hundreds annually by ensuring precise calculations.
Reuse Amazon and other shipping boxes
Cross out old labels and reuse sturdy boxes. This saves packaging costs and is environmentally friendly.
Use bubble wrap sparingly - newspaper works too
Excessive bubble wrap adds weight and cost. Mix bubble wrap for fragile items with newspaper for filling space.
Consider Priority Mail flat rate boxes for heavy items
If your item weighs over 2 lbs and fits in a flat rate box, it's often cheaper than regular Priority Mail pricing.
Cost Saving Tips
Proven strategies to reduce your shipping expenses significantly
Buy Forever stamps in bulk during sales
Forever stamps retain value even if prices increase. Stock up during promotional periods or at warehouse stores.
Use USPS Ground Advantage for non-urgent packages
This newest service replaced several others and offers the best value for packages under 5 lbs traveling long distances.
Ship on Monday-Wednesday for better tracking
Packages ship faster on weekdays and avoid weekend delays. Monday shipments often arrive Friday.
Combine multiple items in one package
Shipping 3 items together is almost always cheaper than 3 separate packages, even with increased weight.
Use online postage for Commercial Base pricing
PayPal Ship Station, Stamps.com, and USPS.com offer discounted rates compared to post office counter prices.
Timing Tips
Optimize your shipping schedule for better results
Ship before 2 PM for same-day processing
Most post offices process packages dropped off before 2 PM the same day. Later drop-offs wait until next business day.
Avoid shipping on Fridays for critical deliveries
Friday packages may sit over weekends. Ship Monday-Thursday for predictable business-day delivery.
Know holiday shipping deadlines
USPS publishes holiday deadlines each year. Ground Advantage typically needs 2+ weeks before Christmas.
Ship early in the month for business packages
Month-end shipping volume increases. Early month shipments move through the system faster.
Use Saturday delivery strategically
Saturday delivery is available for Priority Express. Use it when Monday delivery is too late but Sunday isn't needed.
International Tips
Navigate international shipping challenges
Fill out customs forms completely and accurately
Incomplete or inaccurate customs forms cause delays and can result in packages being returned or seized.
Research prohibited items for destination countries
Each country has different restrictions. Check USPS.com's country-specific guides before shipping.
Use First-Class Mail International for lightweight items
For items under 4 lbs going to most countries, First-Class International is much cheaper than Priority Mail International.
Consider regional rate boxes for heavier international packages
Priority Mail International Regional Rate boxes offer savings for packages to nearby countries like Canada and Mexico.
Include your phone number on international shipments
Customs officials may need to contact you about your shipment. Including a phone number speeds resolution.
Business Tips
Professional strategies for business shipping
Get a business account for Commercial Pricing
USPS business accounts offer 5-15% discounts on most services compared to retail rates.
Use Click-N-Ship for address validation
USPS's online system validates addresses automatically, reducing delivery failures and return costs.
Schedule regular pickups for high volume
Daily pickup service costs less than driving to the post office multiple times per week.
Negotiate postage meter rates for very high volume
Businesses shipping 500+ packages monthly can negotiate better rates with postage meter companies.
Use zone skipping for nationwide shipping
Large businesses can ship pallets to USPS facilities in destination zones, reducing per-package costs.
