New for 2010, the USPS has announced a new pricing structure, Commercial Plus Cubic Pricing, for high volume shippers. Commercial Plus Cubic pricing is based on package size in terms of cubic volume. To qualify for Commercial Plus Cubic pricing, customers must ship more than 250,000 Priority Mail pieces per year. Customers will see significant savings when sending packages that weigh less than 20 pounds and are no larger than ½ cubic foot in volume. Cubic Foot can be calculated by dividing the cubic inches (LxWxH) by 1728.
