Is one allowed to use the unused stamps that were not stamped on the outside of an envelope?
Many times the postcard, letter or packages where there were 5 stamps or less go un-stamped and allows you to remove them and glue them down for another piece of mail you want to mail? Whats your guys take? any Teshuvah on this whether muttur or not or is it plain out gezel?
Not asking can you write GWBR as that would be plain out Gezel or write the return address as the location you want it to go to.
