10 Money-Saving Strategies

1. Use atoship for Rate Shopping

Compare USPS, UPS, and FedEx rates for every package with atoship. Save up to 89% vs retail rates.

2. Right-Size Your Packaging

Every extra inch costs money through DIM weight. Invest in 3-5 box sizes that fit 90% of your products.

3. Use USPS for Lightweight, UPS/FedEx for Heavy

No single carrier wins every scenario. Split your shipping between carriers based on weight.

4. Offer Free Shipping Strategically

Free shipping over $35-50 increases average order value by 15-25% and covers your shipping costs.

5. Ship Ground, Not Express

Most customers are happy with 3-5 day delivery. Express shipping costs 2-3x more.

6. Batch Your Shipments

Pack and ship all orders at the same time for efficiency. Schedule carrier pickups instead of making trips.

7. Use Flat Rate When It Makes Sense

USPS Flat Rate wins for heavy items going to distant zones. Know when to use it.

8. Negotiate After 3 Months of Data

Once you have shipping data, negotiate with carriers. They want your business.

9. Pre-Print Labels at Home

A $100 thermal label printer pays for itself in one month vs. post office trips.

10. Use Poly Mailers When Possible

Poly mailers cost $0.10-0.30 and eliminate DIM weight. Use them for clothing, books, and non-fragile items.

FAQ

What's the absolute cheapest shipping option in 2026?

USPS Ground Advantage starting at $3.50 for packages under 1 lb. For larger items, USPS Flat Rate Envelope at $8.70 beats most weight-based rates for heavy items that fit.

Should small businesses use USPS, UPS, or FedEx?

Use all three. USPS is cheapest for packages under 5 lbs. FedEx/UPS Ground is cheaper for heavier items. Rate shopping software eliminates guesswork.

How do I get commercial shipping rates?

Use shipping software like atoship to access commercial USPS rates without volume requirements. For UPS and FedEx, open a business account and negotiate based on your volume.

Is a thermal label printer worth it?

Absolutely. A $100-200 thermal printer saves $0.05-0.10 per label vs inkjet, eliminates trips to the post office, and processes labels in seconds. ROI within 1-2 months for most businesses.

How much should I charge for shipping?

Offer free shipping with the cost built into product prices when possible. If you charge for shipping, flat-rate ($5-8) converts better than calculated shipping. Set a free shipping threshold ($35-50) to encourage larger orders.
