A few times I have had a buttload of old paperwork type stuff dumped on me. I've taken about an inch thick stack of it (trying to make it as heavy as possible) and stuffed it into a big manila envelope. I then tape an address label cut out of a piece of the stuff, to the front. I then drop it in a mailbox with no return address. I do this with the hope that it will go to them "Postage due", or at least get them called to the P.O. to pick up their package.
