USPS Postal News: Postal Service Mailing Services Prices to Change on May 11
According to the first article,
Prices for mailing services will continue to adjust each May. Prices for most shipping services, including Express Mail and Priority Mail, were adjusted in January and will not change in May.
Some people I know use Forever stamps as freely as they use regular First Class stamps. As a rule, I only use Forevers in extreme emergencies, or in the weeks immediately following a price change until I get new stamps. Ashley, however, pointed out that Forever stamps are most useful on self-addressed stamped envelopes, where you have no control over when your returned item will be posted, and anything sent with insufficient postage will not be delivered.
Hold onto those Forever stamps. They'll be worth more with each passing year. That is, until the United States Postal Service decides that "Forever" has come to an end.
