If you want to buy stamps, you need a comprehensive guide. In this article you will learn where to buy stamps, their advantages and disadvantages, how to recognize fake stamps, the consequences of using fake stamps, how to use stamps correctly, and how many types of stamps there are.

📍 Where Can You Buy Stamps?

USPS.com

Official original products, wide selection. No worry about fakes.  Downside: full price + tax + shipping fees, no discounts.

Stamp Dealers

Good for used stamps and worldwide collections. Check Yellow Pages under "Stamps for Collectors".

Online Marketplaces

Amazon, eBay, Walmart, Etsy — huge variety, even older issues.  Risk of counterfeits. Real stamps rarely exceed 20% discount.

Post Office / Kiosks

Genuine, no extra fee.  Limited hours, fewer designs, long queues. Vending machines being phased out.

CVS / Supermarkets

Walmart, Walgreens, Rite Aid — convenient, open longer.  Stock not guaranteed, limited selection.

💰 How Much is a Forever Stamp Worth in 2026?

Mail Type Current Price (2026)
Domestic Forever Stamp (1 oz letter) $0.78
Additional Ounce (single-piece) $0.28
Postcard Stamp $0.61
Global Forever Stamp (1 oz international) $1.70

⚠️ How to Identify Fake Stamps & Consequences

Real stamps fluoresce under UV light. Counterfeits are often sold on Facebook, eBay, and unauthorized sites. A discount of 30–50% off face value is a major red flag.

Federal Crime: Making or knowingly selling counterfeit postage is punishable by fines and/or up to five years in prison. Mail with counterfeit stamps will be returned marked "COUNTERFEIT POSTAGE" — causing serious delays.

✉️ How to Use Stamps Correctly

Step 1: Choose Envelope or Postcard

Standard rectangular shapes cost less. Non-rectangular, square, or rigid envelopes require extra postage.

Step 2: Write Address

Place recipient address in the center, return address top-left, stamp top-right corner.

Step 3: Calculate Postage

Use the USPS Postage Calculator. Factors: destination, weight, shape, special services.

Step 4: Mail Your Letter

Drop in blue collection box, give to mail carrier, or bring to post office. Ensure sufficient postage; otherwise it will be returned.
