Back in April, shortly before the most recent rate increase for first class postage, I took advantage of the opportunity and stocked up on “Forever” stamps at the 41-cent price.
The rate went up to 42 cents on May 10. Since then, I figure I’ve probably used about 200 of them. That’s a savings of $2 on an $82 investment. Granted, 2.4% doesn’t seem like much, but that’s pretty fantastic compared to the return on my 401k during the same period.
