Boxing match

Priority Mail boxes.The Postal Service has launched a new, larger Priority Mail box, and it’s already proving to be very popular.

The new Priority Mail Large Flat-Rate Box — its official name — is 50 percent bigger than cur­rent boxes. It holds nearly 800 cubic inches. Like other flat-rate products, it gives customers one price — $12.95 to any U.S. destina­tion — while letting them ship more, regardless of weight.

When shipped to an APO/FPO destination, these boxes cost $10.95, a $2 savings. Some of the new boxes feature the logo of America Supports You, a Department of Defense program offering support to military members and their families. Either version of the box is eligible for the dis­count, as long as it’s sent to an APO/FPO address.

Demand for the military-branded boxes has been higher than anticipated. Nearly 40 percent of the more than 800,000 boxes shipped since Feb. 20 has been cobranded boxes. Post Offices began stocking the larger boxes March 3. Customers can also order them by calling 800–610-8734 or through USPS.com.
