Shipping mistakes that kill profit
Most resellers don’t lose money on fees — they lose it on shipping. Here’s what to watch.
The #1 killer: dimensional weight
Large, lightweight boxes can cost more than small, heavy boxes. Always consider box size, not just weight.
Carrier selection basics
- USPS Ground Advantage: great for 1–15 lb items
- USPS Priority: good when speed matters; flat rate only when it wins
- UPS/FedEx Ground: often best for bulky or 5–40 lb items
Packaging reduces returns
- Use padding and sturdy boxes for electronics
- Photograph condition and packaging for disputes
- Insure items over $100
