Reviewed September 12, 2026. Ordinary Forever stamps simplify planning because one unused stamp continues to cover a qualifying one-ounce First-Class Mail letter after the ordinary letter rate changes. They do not eliminate the need to check the finished mailpiece.
1. Forecast actual letter volume
Estimate qualifying U.S. one-ounce letters by month. Separate heavier, square, rigid, oversized and international pieces because they can require different postage.
2. Calculate use-value, not an investment return
If a future ordinary letter rate is higher, a stamp bought earlier can produce a use-value difference when you actually mail it. Formula: planned stamps used × future rate difference. The future rate is uncertain, and the calculation does not prove resale profit.
3. Keep a practical inventory level
Balance fewer reorders against cash tied up in unused postage. Businesses with stable invoices or correspondence can set a reorder point; occasional mailers may need only a small reserve.
4. Store stamps carefully
Keep panes and booklets dry, flat and away from heat or pressure that can damage adhesive. Storage loss reduces any expected convenience or savings.
5. Recheck exceptions before mailing
Destination, shape, dimensions, thickness, rigidity, weight and extra services determine the total. International mail cannot be reduced to a fixed “three or more stamps” rule; calculate the actual category and current price.
What this strategy does not claim
- No claim that each stamp was individually authenticated by a proprietary process
- No automatic environmental benefit without lifecycle evidence
- No guaranteed inflation hedge or liquid resale value
- No promise that one stamp covers every letter
