Stamp prices are traditionally in whole cent increments. That means it is difficult to target a particular percentage increase. For instance, a one-cent increase on the 42-cent stamp would have been 2.4 percent; while the two-cent increase was 4.8 percent.
Since the earliest days of the Post Office there has been a public policy goal of promoting the dissemination of information throughout the country. This goal was also part of all 14 of the rate cases conducted under the Postal Reorganization Act. By law, rates had to consider “the educational, cultural, scientific, and informational value to the recipient of mail matter.” This provision generally tempered the increases for Periodicals, or at least kept the “institutional cost burden” for Periodicals to a minimum.
Sale is not a word usually associated with the Postal Service, but there is a first time for everything. Mail volume has dropped significantly this year, and the Postal Service is proposing a “Summer Sale” to encourage mailers to send more Standard Mail. The Postal Service believes it can use its excess capacity to deliver the additional mail volume at a relatively low cost.
