USPS First-Class Mail® International Letter costs $0.98. Can I drop it into a USPS mailbox with a stamps value of $1.32?
I’m tired to stay in a line every time for this 1 dollar. Is that OK if I stick 3 stamps by 44 cents on the envelope and drop this envelope into any USPS mailbox?
So the price of stamps is not a question. The question if it’s allowed.
Who knows for sure?
Please don’t try to earn points answering the question if you didn’t do that. That’s very important.

Thank you.

Yes, you can do that.
