Your comment made me think of the Terry Pratchett book "Going Postal" in which a conman is put in charge of the post office and quickly realizes what you said: selling stamps is free money. One of my favorites from his later discworld books.

Yeah, they are little more than the sticker books you buy for kids.

And I had a 3-year-old who proudly showed me the toy covered in "stickers" after he found a book of 100 $0.48 stamps!
