least expensive shipping for heavy items

least expensive shipping for heavy items is usually ground shipping or freight services, depending on the item’s size and distance. USPS Retail Ground, UPS Ground, and FedEx Ground offer affordable options for domestic shipping. For extremely heavy items or bulk shipments, Less Than Truckload (LTL) freight services might be more cost-effective. Rate comparison tools and third-party shipping platforms like Shippo or Pirate Ship can help identify the best pricing across carriers. Choosing slower delivery speeds also significantly reduces cost.
