Mail carriers will be delivering some good news and so
me bad news this week.
The bad news: Stamp prices are expected to rise 2 cents in May to 41 cents, the Postal Regulatory Commission announced yesterday. The good news: With the introduction of a “forever stamp,” it may be the last time Americans have to use annoying 2-or 3-cent stamps to make up postage differences.
Beginning in May, people would be able to purchase the stamps in booklets of 20 at the regular rate of a first-class stamp. As the name implies, “forever stamps” will keep their first-class mailing value forever, even when the postage rate goes up.
