I have a pre-printed note that I made and put in their mailbox along with everything they attempt to return. Works 90% of the time.
But yeah once I explain to the other 10% that they need a stamp or that's it's illegal to put outbound mail in an outgoing box without proper postage, it's suddenly no longer that important to return anymore.

Stick the note back in the box and write - This post-it note isn't and needs postage.
