While U.S. Post Offices aren’t open on Sundays, USPS self-service kiosks offer a convenient way to buy stamps and send mail outside of regular business hours.[1]
Several major retailers like Walmart and Kroger also sell stamps, allowing you to complete multiple errands in one stop.[2][3]
Below, I list where to buy stamps on Sundays (including available quantities).
What I Recommend
The best place to buy stamps on Sunday is your local U.S. Post Office. Although Post Offices close on Sundays, most lobbies are open and have self-service kiosks that sell stamps and postage for parcels.[4]
While you’re there, you can also drop off letters or parcels for USPS to process the next day.[4]
You can immediately apply the postage and drop your item in the dropbox instead of waiting for pickup or making an extra trip to the post office on a weekday.[4]
If your local Post Office doesn’t have a self-service kiosk, Walmart will likely be your best option; it’s local to most and is typically open from 6 a.m. to 11 p.m. on Sundays.[2]
The List
You can buy postage stamps at the register at the following places. Stamps are typically available for purchase during regular business hours, seven days a week.
I confirmed this information by contacting customer service representatives for each company and viewing online policy documentation.
The list below is in order beginning with the best options based on convenience and widespread availability.

FAQ

Forever stamps don’t have an amount printed on them and you can continue to use them to mail letters even after postage prices rise.[1]
If your letter weighs more than one ounce, you will need additional postage.[23]

You can also purchase stamps on Sundays at several major retailers, such as Kroger and Walmart.[10][2]
