Some good news has come along with the bad news that it soon will cost 39 cents, instead of the present 37 cents, to mail a one-ounce letter. The U.S. Postal Service is studying a proposal to offer a "forever" or "perpetual" stamp, which could be used regardless of future postage increases.
You could stockpile a bunch of these stamps for future use and never have to worry about their getting out of date. And when the price of a stamp went up, you wouldn't have to buy a supply of, say, two-cent stamps to make up the difference. Your old "forever" stamps would still be good.
A group working on the issue is slated to report its findings by next July. One question is the financial impact of the scheme on the Postal Service.
