You can buy postage stamps from several convenient places:

• Your local post office is the most common place to buy stamps. Many post offices also have self-service kiosks for quicker purchases

• Online from official postal services like USPS.com in the US or Deutsche Post in Germany, where you can order various stamp designs and formats

• Retail stores such as grocery stores, pharmacies, office supply stores, and big-box retailers like Walmart often sell stamp booklets

• The UPS Store locations offer USPS postage stamps and other mailing services as a convenient alternative to the post office

• Some banks and credit unions sell stamps at their ATMs or teller windows, though availability varies by location

• In Germany, you can also buy stamps at kiosks, convenience stores (Späti), BVG shops, and vending machines outside post offices. Digital stamps via SMS or printing stamps online are additional options

So depending on your location, you can get stamps at post offices, online postal stores, retail shops, convenience stores, or specialized mailing service stores.
