You need exactly one stamp for one envelope. Everywhere you look, stamps come packaged in a book of 20 for $16.40. Knowing where to buy single stamps saves you from paying for 19 you do not need.
The post office counter is your most reliable option. A retail clerk can peel a single Forever stamp off a sheet. It costs $0.82, no book required.
Self service kiosks and most retail stores are a different story. That is where people get tripped up looking for where to buy single stamps, and I would not bother trying there first.
Buying one stamp at the post office counter
This is the one place that will sell you exactly what you ask for. Walk up and tell the clerk you need one stamp. They ring up $0.82 for a single Forever stamp.
Clerks keep loose sheets and partial books behind the counter for this exact reason. You can ask for a specific design too, within whatever stock the office has that day.
Smaller post offices run lean on variety near the holidays. If the clerk only has flags left, you are getting a flag. The stamp works the same either way.
Want the fuller picture of every counter, kiosk, and retailer that carries stamps? Our full guide to where to buy stamps covers them side by side.
Self service kiosks: do they sell just one
Self service kiosks sit in the lobby of many post offices. USPS describes them as a place to buy stamps, weigh a package, and print a shipping label without waiting for a clerk.
In practice, kiosks are built to move a full book, not to peel off a single stamp. USPS does not publish a quantity rule for them, and I could not confirm that any model vends a lone Forever stamp.
Some units will print a postage label for one letter instead. That does the same job if you are mailing it today.
If the kiosk near you only sells books, skip the machine and get in the regular line. A human behind the counter can always sell you one stamp even when the machine cannot.
Grocery stores, pharmacies, and other retailers
CVS, Walgreens, Kroger, and thousands of other stores carry stamps through the USPS retail partner program. Almost all of them stock sealed books of 20, not loose singles.
A cashier at these stores generally will not tear open a $16.40 book to sell you one $0.82 stamp. The inventory system tracks whole books. Breaking one open creates a headache nobody at the register wants.
Small independent shops, corner stores, and some gas stations behave differently. Their regular customers often want just one or two stamps for a bill or a card. A shop owner there is more willing to sell from an open book.
Chains like Walmart and Target stock stamps too, but the book only rule still applies. See our notes on what Walmart actually stocks at the till and how CVS handles stamp sales if you are deciding which stop to make.
The partner program was built to move full books at scale. Nobody at USPS designed it around a single stamp sale at a register, and the stores act like it.
Stamp vending machines
Coin operated stamp machines used to sit in post office lobbies, airports, and drugstores. Most are gone now. USPS has been pulling them out for years in favor of kiosks and retail partners.
A few older machines still turn up in rural offices or old buildings. The ones I have heard of dispense a book, not a single stamp, sometimes at a markup. Do not plan a trip around finding one.
Can you buy a single stamp online
The Postal Store on usps.com sells stamps in sheets, books, and coils. The smallest order for most designs is a full book of 20.
There is no listing anywhere on the site for one loose Forever stamp shipped to your door. That makes sense once you think about the shipping cost on an $0.82 item.
Mailing one stamp would cost more in postage than the stamp is worth, so I doubt that listing ever appears. If you are pricing a full order instead, our stamp calculator figures out books, sheets, and coils fast. And read how ordering stamps online actually works before you count on a fast delivery.
What to do when you just need one letter out today
Sometimes the real problem is the deadline, not the stamp. If you are already at the counter, hand the clerk the envelope and pay for postage. The clerk prints a postage label right onto it, and you never touch a stamp.
That label costs the same $0.82 as a Forever stamp for a 1 ounce letter. The cheaper $0.78 metered rate only applies if you run your own postage meter or online postage account. That is overkill for one card.
Click-N-Ship is not the answer either. It is built for packages, not a single First-Class letter.
Curious what a book actually costs compared to buying single stamps one at a time? Our breakdown of current stamp prices lays out every format.

Bottom line on where to buy single stamps
The post office counter is where to buy single stamps with zero hassle. A clerk sells you exactly one, priced at face value, every time.
Kiosks, retail stores, and the online Postal Store are built around full books instead. Treat those as a backup plan, not your first stop.
Cannot find a single stamp anywhere and the letter has to go out now? Ask the counter clerk to print the postage on the envelope instead.
