least expensive way to ship heavy boxes

least expensive way to ship heavy boxes depends on the size, weight, and destination of the package. For heavier items, the most affordable shipping methods typically include USPS Priority Mail, UPS Ground, and FedEx Ground. USPS offers discounted rates for heavy boxes through their Priority Mail service, which includes free packaging and delivers within 1-3 business days, depending on the destination.
