From the Ideas Whose Time Have Come Department: the Forever Stamp.
The forever stamp goes on sale April 12 at 41 cents. The rate for first-class postage rises to 41 cents May 14.
The stamp, which will carry the word "Forever" instead of a price, will remain valid for sending a letter, no matter how much rates go up in the future.
That will eliminate the annoyance of buying one- and two-cent stamps to make up the new rate when prices rise, and folks who want to hedge against inflation could lay in a supply of the stamps for long-term use.
