The Governors of the US Postal Service have approved another hike in the price of a stamp, raising the cost of a First-Class Stamp from 39 cents to 41 cents. At the same time, they approved the issuance of the “forever” stamp.

The “forever” stamp will sell at the 41 cent one-ounce letter rate but will remain good regardless of any future price changes. The value of the “forever” stamp will always be the one-ounce letter rate, and can be used on any future one-ounce letter mailing without extra postage even if the rate has increased.

If you still write letters and send them snail mail or if you still pay some or all of your bills by mail, this might be a no-brainer of an investment. The “forever” stamp costs the same as a regular postage stamp but will be good even if you use it ten years from now. Chances are you will still be paying bills ten years from now and it’s certain that the price of postage will go up in that time.
