Just read about this interesting inflation "hedge":
Forever Stamps - What Are Forever Stamps?


Forever Stamps are first-class stamps issued by the United States Postal Service. What makes them special is that you can buy them at the current first-class postage rate, and they remain valid even if that rate rises in the future.

If you assume postal rates will always rise and never sink, then Forever Stamps are a good investment. :wave:

If you enter mail-in sweepstakes, buying Forever Stamps can protect you from the additional risk associated with rising postage stamps.

Forever Stamps can be purchased from the United States Postal Service at your local post office, online, or by telephone.

The Canadian Post offers a similar product, the Permanent Stamp.

Seems to be a great investment:
