Comment on Would not adding a stamp and return address on a letter give you free postage

Yeah I heard that one before. Another was using a stamp but putting a layer of Elmer’s glue over it, which stopped the cancellation ink from getting on the stamp. The recipient would wash off the glue and re-use the stamp (covering it with more glue the same way) to write back to you. I never tried that myself but I knew people who claimed to have done this in real life, with 1 cent stamps even.

This one doesn’t work anymore. I did this accidentally because I had misaddressed an envelope very badly and decided to use a new envelope. I peeled the stamp off it (one of the sticker ones) and used glue to put it back on the envelope.
The post office returned it to me with a note saying that the stamp could not be used as the ultra violet mark they use to validate stamps couldn’t be seen through the glue.
