best shipping rates for large packages

best shipping rates for large packages Best shipping rates for large packages depend on weight, dimensions, and distance. USPS offers cost-effective ground options, but UPS and FedEx may be better for heavy or oversized parcels with negotiated rates. Third-party tools like Shippo or Pirate Ship help compare carriers and access commercial discounts. Regional carriers or freight services may also provide better pricing for bulkier shipments. Properly measuring and classifying the package helps avoid surcharges and optimize your shipping strategy for savings.
