What is the cheapest way to ship packages?

Updated October 2026 · How we answer

Short answerThe cheapest way depends on package size, weight, destination, and speed. For small, lightweight items, USPS Ground Advantage or Media Mail (for books) is often cheapest. For larger or heavier packages, FedEx or UPS ground services may be cheaper, especially with negotiated rates through a reseller platform or third-party service like Pirate Ship or ShipStation.

Compare Carrier Rates

The cheapest option varies by package. USPS Ground Advantage is typically best for packages under 1 lb and up to 20 lbs, but prices increase with distance. FedEx and UPS ground are often cheaper for heavier packages (over 5 lbs) or when shipping to commercial addresses. Regional carriers like OnTrac or LaserShip can be cheaper for specific zones.

Always compare rates using a shipping platform like Pirate Ship, ShipStation, or Stamps.com. These services offer discounted rates that can be 20-40% lower than retail counter prices. For books, CDs, and DVDs, USPS Media Mail is usually the cheapest but is slow and restricted to media items.

Use Flat-Rate and Regional Options

If your item fits in a USPS Flat Rate envelope or box, that can be cost-effective for heavy items because the price is based on package size, not weight. However, for lightweight items, flat rate may be more expensive than weight-based options.

Regional rate boxes (available for some USPS services) can be cheaper for short-distance shipments. Also consider using poly mailers for soft goods to reduce weight and dimensional weight charges.

  • USPS Ground Advantage: good for small, light packages.
  • USPS Media Mail: cheapest for books and media.
  • FedEx/UPS Ground: often better for heavier packages.
  • Regional carriers: may be cheaper for specific routes.
  • Shipping platforms: give discounted rates.

Common mistakes

  • Assuming one carrier is always cheapest; rates vary by weight, size, and destination.
  • Overlooking dimensional weight, which can make large but light packages expensive.
  • Paying retail counter rates instead of using discounted online postage.
