Open a magazine, or the mail, and pre-paid postage envelopes gallop out like lemmings.
Besides recycling them, which I do with glee, can't we regift them to mail a snail mail letter to Uncle Rube, or hate mail to the mega church for using their electric marquee for political statements? I think just a sticky label over the address of "Committee to Reelect Congressman Wealth Nutts" and sha-zam your saving damn near half a dollar, and Rep. Nutts's oil lobby picks up the tab.
OK I am relying on tribal knowledge here, will it work? Is there anything illegal about it, mail fraud or something? I assume you also must cover the barcode like string along the base of the envelope, which I believe is the coded address.
Anyone? Can it be done? Legal?
