The Verdict

USPS is the winner for most penny resellers. Priority Mail Flat Rate boxes are a game-changer: pay one fixed price regardless of weight (up to 70 lbs) for cross-country shipments. For items under 1 lb, USPS First Class is the cheapest option available. UPS and FedEx become competitive for packages over 5 lbs traveling short distances. Use eBay or Pirateship for discounted USPS rates that can save 15-50% versus counter prices.

Frequently Asked Questions

What is the cheapest way to ship a penny item?
For items under 1 lb, USPS First Class Package is typically the cheapest at $4-$6 with platform discounts. For heavier items up to 5 lbs, USPS Priority Mail Flat Rate envelopes ($9.85 commercial rate) often beat other carriers. Always compare rates before purchasing a label.
What is Pirateship and should I use it?
Pirateship is a free shipping software that gives you access to USPS commercial plus rates — the same discounts large businesses get. For penny resellers not using Amazon FBA, Pirateship can save 10-20% versus eBay shipping rates on USPS labels. It is free to use with no monthly fees.
