Most post offices offer two ways to buy: the counter, and a self-service kiosk in the lobby. They are not equivalent, and knowing the difference saves a wasted trip.
The counter
Full range, including commemoratives and specialty denominations, and a person who can answer questions.
That last part is the real value. Tell a clerk what you are sending and they will recommend the right stamp — which matters most in exactly the cases where guessing goes wrong: heavy items, unusual shapes, international mail.
The constraint is hours. The counter keeps business hours and closes.
The kiosk
Self-service machines handle stamp purchases with on-screen guidance, and many post office lobbies stay open long after the counter shuts — which makes the kiosk the answer to "I need a stamp at nine in the evening".
The trade-off is selection. Kiosks carry a reduced range: standard denominations, a small number of designs, and generally none of the commemoratives or specialty rates.
So the kiosk is right when you need postage and wrong when you need a particular stamp. If you are matching a design to an invitation suite, do not drive to the lobby at night expecting to find it.
Everywhere else
Supermarkets, pharmacies, convenience stores and banks commonly stock standard booklets at face value. Convenient, limited to one or two designs, and open when the post office is not.
Online, the official store carries the complete catalogue and delivers in a few days. Verified surplus dealers sell below face and carry retired designs. Large marketplaces work if you check the individual seller's record.
Whichever you use online, buy from an established channel. Counterfeits are the one risk that is entirely avoidable by choosing where you shop.
Which to use
| What you need | Where to go |
|---|---|
| A stamp tonight | Lobby kiosk, or a late-opening shop |
| Advice on the right rate | The counter, with the item in hand |
| A specific design | The counter or the official online store |
| A retired design | Verified surplus dealer, or a stamp dealer |
| Volume, below face | Verified surplus dealer |
One correction while we are here
Post offices, banks and convenience stores sell stamps. None of them buy them back.
If you are trying to sell a collection, the buyers are stamp dealers, auction houses, collectors at clubs and shows, or online marketplaces — not the places you bought them from. Turning up at a counter with a box of stamps will not produce an offer.
Best deals on Forever stamps
All the convenience channels charge face value, which is correct for a booklet and expensive as a routine. Below-face buying starts to matter once you are purchasing monthly rather than occasionally.
Where to buy
The USPS official store, or a verified surplus channel such as Forever Stamp Center for volume and older designs.
The short version
The kiosk is open late and stocks few designs; the counter has everything and closes at five. Match the channel to whether you need postage or a particular stamp — and remember that none of them will buy stamps back from you.
