A courier firm took a contract to mail 20,000 invitations on an 18% margin. Mid-job, the stamp rate went up by $0.05.
Five cents. Across 20,000 pieces, plus rush purchasing because nothing had been stocked ahead, the margin fell to 4%. All the work, all the risk, and almost none of the profit.
Pre-buying postage is cost control, not investing
Worth being precise here, because this gets oversold. A Forever stamp stays valid for a one-ounce letter whatever the rate becomes. Buy postage before an increase and you pay the old price for mail you send afterwards.
That is a hedge against a cost you will definitely incur. It is not an investment: you cannot redeem stamps for cash at the new rate, and the gain exists only as postage you actually use. Buy more than your operation will consume and you have not earned anything — you have converted cash into a slow-moving supply.
Within that limit the arithmetic is real. Ten thousand stamps bought at a surplus $0.62 and used after the rate reaches $0.82 is $2,000 of avoided cost on mail that was going out regardless.

Buy in your quiet months
For a seasonal business the timing matters as much as the price. Placing bulk orders in the slow months — for a convention-driven courier, May and November — covers roughly 50% of projected annual volume without landing a large expense in the months when payroll is already at its heaviest.
Keep a separate small reserve bought at retail for genuine emergencies, and do not raid the pre-bought stock for rush jobs. Once you burn the hedge on an emergency you are back to buying at whatever the rate is that morning.
The discount ceiling
A useful firewall: above 25% off is a scam; at or below 25% is plausible verified surplus. A batch bought at $0.35 to test the theory turned out to be stickers.
| Situation | Buying on the day | Buying ahead | Difference per 10,000 |
|---|---|---|---|
| Rate increase | Pays $0.82 | Uses stock at $0.62 | $2,000 |
| Rush order | Retail at $0.78 | Uses stock at $0.62 | $1,600 |
| Counterfeit risk | $0.35, seized | Verified, delivered | The contract |
What it added up to
Across a year, the gap between buying reactively and buying ahead came to $11,800 — enough for the down payment on a van, out of a line nobody had previously managed at all.
Rate history and adjustment timing are published in the USPS financial reports, with proposed changes reviewed by the Postal Regulatory Commission before they take effect — which is where the notice period comes from.
Where to buy
The USPS official store for the emergency reserve, or a verified surplus channel such as Forever Stamp Center for the planned bulk purchase.
The short version
Forecast your annual postage, buy it in your slow months at a defensible discount, keep a small retail reserve separate from it, and cap any discount at 25%. Buy what you will use — beyond that it stops being a hedge and starts being inventory.
