Risky investments and rising prices seem to be everywhere these days

For the past year, branches have been selling “The Forever Stamp” for 41 cents each

“The stamp will be good for mailing one-ounce First-Class letters anytime in the future — regardless of price changes,” the agency promises.

As the penny increase of May 12 nears, the forever deal is proving irresistible to millions of Americans, according to today’s news release:

In the past several weeks, Postal Service customers have been buying Forever Stamps at a rate of about 30 million per day, bringing the amount sold to more than 6 billion since they were first offered.

The Associated Press further detailed the climb, reporting forever stamp sales of $267,696,023 in March, $207,900,132 in February and $115,303,031 in January
