Key takeaways

Shipping can quietly eat your profit, especially on low-priced items. A few habits make a big difference.

1. Weigh and measure everything

Buy a small shipping scale. Carriers price by weight and size; many use dimensional weight, charging large, light parcels as if they were heavier. Smaller boxes often save money.

2. Use discounted labels

Marketplaces and shipping software often offer discounted labels compared with buying at the counter. Compare options for each parcel.

3. Compare service types

Flat-rate boxesHeavy, small items
Weight-based servicesLight items
Economy or ground servicesNon-urgent, low-value items
ExpressTime-sensitive or high-value items

4. Right-size your packaging

  • Use poly mailers for clothing and soft goods.
  • Reuse clean boxes where appropriate.
  • Protect fragile items with enough padding; a broken item costs more than extra bubble wrap.

5. Build shipping into your price

Decide whether to charge shipping separately or offer “free” shipping with the cost built into the price. Buyers often prefer free shipping, but make sure the maths works; see pricing used items.

6. Always use tracking

Tracking protects you in disputes and is often required by marketplace seller protection.

7. Batch your shipping

Print labels in batches and schedule pickups to save time.
