Yesterday I opened an envelope from a school and found an invoice with a dime taped to it. My company had sent an invoice for $0.10 to a school, and this was their response. It seemed fair to me.
Later I got a letter from a customer with a $0.41 cent stamp on it, and a penny taped next to the stamp, in lieu of postage. Apparently you can do that, and it works. Or maybe the postal inspector was feeling generous.
Apparently, Thursday, May 15th was Tape a Coin to a Document Day. No one told me!…With words.
