Okay, so I screwed up. I needed stamps, the local post office I knew of is closed during my work hours, so I ordered some on Amazon. When they showed up, I realized that they were postcard stamps.

I could send them back, but that would be a hassle. Can I send a regular letter by putting two of them on the envelope? Is there any other way to use them? (I don't see sending postcards any time soon.)

P.S. I am not at all sure this is the right kind of question for this site. If you know of a SE site where it would fit better, feel free to send this there.

    Honestly this doesn't sound like a question for lifehacks. I would recommend looking on the web page of the mail services that operate in the respective country where you are trying to send the letter from.

Stamps are stamps, at least in the United States. Right now, your post card stamps are worth 34 cents each, and a typical letter costs 49 cents to mail. So yes, you can put 2 postcard stamps on a regular letter to mail it.

    You could also go into an open Post Office and buy 15 cent stamps, or a combination of 10 and 5 cent stamps. These seem like odd denominations, but they're still sold as make-up stamps -- to make-up an amount for which you don't have an exact match. They even still sell one cent stamps.
