The USPS is proposing a price change for priority mail come September 2014. However, it's not adverse - in fact, it can change commercial pricing so that companies save more by shipping through the USPS!
It seems almost too good to be true, but it isn't. Some of these rate reductions are over 50% savings! The trend is that a lot of commerical packages are already light - in fact, they only average 2.3 lbs a package! So it shouldn't actually cost as much to ship, even if you're shipping up to 40 pounds. The USPS offers savings on commercial mail, particularly being reduced in ranges between 3 and 40 pounds, and you can expect to spend LESS now on this mail than you did in 1991!
This huge savings cost can change so much for your commercial mailpieces. Click here to see the proposed changes from USPS!
