How to Buy Stamps Online — Books, Singles, and Print-at-Home

You can order stamps online and have them delivered, or skip the physical stamp entirely and print postage directly onto an envelope from your home printer.

Where to buy books of stamps online

Forever stamps come in books of 20 or coils of 100. Priority Mail and Global stamps come in sheets of 4, 10, or 20.

These retailers sell stamps online and ship to your door:

• USPS online store — the official source. Widest selection of designs and denominations.
• Amazon — sells books and coils with Prime shipping.
• Walmart — available online and in-store at the customer service desk.
• Costco — sells coils of 100 at a slight discount for members.
• Office Depot — carries Forever stamps and specialty stamps.

None of these retailers sell individual stamps online — the fulfillment cost would exceed the stamp price. If you need just one, buy it at a post office or print one at home (see below).

How to print postage for a single letter

You cannot buy a single physical stamp online, but you can print postage for a single letter at home. The result is a USPS-approved barcode label that replaces a traditional stamp.

Stamps.com is the main platform for this. Sign up and get a special postage offer worth up to $100 in value. It prints postage on standard #10 envelopes and other sizes, and offers discounted commercial rates — you pay less per letter than the retail price.

Stamps.com also offers NetStamps — USPS-approved peel-and-stick labels that you print First-Class Mail postage onto using any home printer. You buy blank NetStamps sheets or rolls, print the postage amount onto them, and stick them on envelopes, postcards, or other First-Class Mail. They work like traditional stamps but you print them on demand, so you only pay for what you use and never overpay when rates change.

NetStamps come in dozens of themed designs — holiday (Warm Wishes, Frosty Hot Cocoa, Pumpkins Galore), seasonal (Spring Blossoms, Sunflower Sky, Fall River), patriotic (Stars & Stripes, Bald Eagle), and thank you designs. Sheets start at $6.99 for 120 labels.

Enter your “To” and “From” addresses, and the software prints everything — postage, barcode, and addresses — directly onto the envelope or label.

You can also add custom branding — your logo, return address graphics, or business name — to envelopes and labels.
