Amazon Deal With USPS Gives Sellers Unprecedented Discounts

Amazon.com told sellers on Monday it had negotiated a deal with the USPS so they will see no rate change on the cost of Priority Mail shipping, which will remain at 2015 rates. The deal is unprecedented, since Priority Mail rates increased 9.8 percent on average as of Sunday, and an increase of 9.4 percent for Commercial Base pricing, on average.
