“We listened to our customers, and we’re giving them a new box that lets them ship larger items while still enjoying the benefits of a flat rate,” said Postmaster General John Potter. “Flat-rate boxes are very popular and the new, larger version provides even more value.”
The new Priority Mail Large Flat-Rate Box (12" x 12" x 5½") can be used for both domestic and international shipments. This extends the flat-rate price and ease-of-use benefits to international shippers. There is also a 5 percent online discount.
There will be a special version of the box for the military, with a $2 discount, if shipped to an Army Post Office or Fleet Post Office (APO/FPO) address.
All Postal Service Priority and Express Mail packages and envelopes are environmentally friendly, exceeding the highest standards for recyclability.
