Even enterprise retailers such as Amazon and Walmart use the service. Today, USPS flat rate services address many ecommerce delivery problems and costs. More than a decade later, on November 20, 2004, the USPS released the Priority Mail flat-rate box. The postal service’s flat-rate offering began in February 1991 when it introduced the Priority Mail flat-rate envelope. Shoppers expect to place an order, obtain free shipping, and receive that order in about two days.įortunately for merchants, the USPS is a leader in flat-rate shipping services. Most online stores now offer free shipping - thank Amazon, L.L. Moreover, free and fast ecommerce delivery is ubiquitous. A business must pay shipping and carrier fees, buy packing materials, and hire labor to pick and pack each order. Shipping can be a significant challenge for ecommerce merchants. That is the exact cubic dimension of your package.For more than 20 years, the United States Postal Service has offered flat-rate boxes and envelopes that have helped online stores reduce shipping costs while improving shoppers’ buying experience. Multiply the Length, Width, and Height, and then divide that total by 1,728. For boxes that aren't square, measure the Length, Width, and Height of your box in inches. A 2 cubic foot square box is pretty big and well beyond the size of most packages being shipped. A square package 2 feet by 2 feet is 2 Cubic feet. A square package 1 foot by 1 foot is 1 cubic foot. *Calculating the cubic dimensions of your packages isn't difficult. And when shipping packages, select Large Package. We suggest reviewing your shipping process to ship in the smallest box possible to avoid these surcharges. If the volume of the package is greater than 2 cubic feet, a $15.00 surcharge will be applied*.If the longest side of a package is greater than 30 inches, a $7.00 surcharge will be applied.Packages with missing or incorrect package dimensions that result in any dimensions-based fees, a $1.50 surcharge will be applied.If the volume of the package is greater than 2 cubic feet, a $25.00 surcharge will be applied*.If the longest side of a package is greater than 30 inches, a $15.00 surcharge will be applied.If the longest side of a package is more than 22 inches but less than 30 inches, a $4.00 surcharge will be applied.
