How people make money on Forever Stamps

The price of a first-class stamp will increase one penny to 42 cents tomorrow, the U.S. Postal Service said in a reminder on its Web site.

Prices for other mailing services, including standard mail, periodicals, package services and special services, will also increase tomorrow, the Postal Service, an independent federal agency, said. The agency first announced the price increase on Feb. 11.

Forty-two-cent stamps will be required on first-class mail weighing an ounce (0.02 kilograms) or less, while first-class mail weighing as much as two ounces will increase 1 cent to 59 cents, the Postal Service said.

The last first-class mail increase was in May 2007, to 41 cents from 39 cents.

Postal Service offers "Forever Stamps." Buy them at today's rate and they're good, well, forever.

Buy them this week at 41 cents and next week, when the rate is 42, they're still good -- and will be five or 10 years from now. Buy as many as you like. The Postal Service said it would have 5 billion in stock before the penny increase on May 12, 2008.

A guy in Camp Hill, Pa., bought $8,000 worth last year. That's 19,512 stamps, and change.

Come Sunday he'll have a 2.44 percent return on that money -- better than the stock market this year.

Buy now and get a bargain.
