How to Save Money on Shipping Supplies in 2026
Shipping supplies are a hidden cost that adds up fast. A box here ($1.50), tape there ($0.50), bubble wrap ($0.30) — per package, it seems small. But at 500 packages/month, you're spending $1,150/month just on materials. Here's how to cut that in half or more.

Cost-Cutting Strategies
1. Reuse Incoming Packaging
Save boxes, bubble wrap, and packing peanuts from your own deliveries
Remove old labels and tape
Savings: $0.50-2.00 per package
2. Use Poly Mailers Instead of Boxes

3. Right-Size Your Boxes
Using a box 2" too large on each dimension can cost:
Extra packing material: $0.30-0.50
DIM weight surcharge: $2.00-5.00
Total waste: $2.30-5.50 per package
4. Switch to Kraft Paper
Kraft paper (crumpled) replaces bubble wrap for many applications:
Cost: $0.05-0.10 per package vs $0.20-0.40 for bubble wrap
Eco-friendly: recyclable and biodegradable
Effective: provides good cushioning for non-fragile items

FAQ
Are USPS Priority Mail boxes really free?
Yes — USPS delivers free Priority Mail boxes, envelopes, and tape to your door. Order at usps.com/shop. The only requirement is that you use them for Priority Mail or Priority Mail Express service.
Where can I get free boxes for shipping?
USPS offers free Priority Mail boxes. You can also get free boxes from grocery stores, liquor stores, and retail stores that discard packaging daily. Ask during morning restocking hours.
Is it cheaper to buy shipping supplies on Amazon or Uline?
Amazon is cheaper for small quantities (under 50). Uline is cheaper for bulk orders (100+). For very high volume (500+), contact packaging manufacturers directly for the best per-unit pricing.
Should I invest in an air pillow machine?
If you ship 200+ packages per month, an air pillow machine ($300-500) pays for itself within 2-3 months. Air pillows cost $0.02-0.04 each vs $0.15-0.30 for equivalent bubble wrap.
How much do shipping supplies cost per package?
Average cost ranges from $0.80 (poly mailer + tape) to $3.50 (box + bubble wrap + tape + packing material). Right-sizing packages and buying in bulk can reduce this by 30-50%.
