if you move . . .
and don’t tell us in advance of your address change, it causes a surprising waste of resources. The post office does not forward bulk mail; instead it destroys the undelivered literature. Then we usually receive a notice from the post office saying that you have moved, and we are charged postage due for the notice. This need not happen if you will kindly let us know of your address change with as much advance notice as possible. You can e-mail address changes to <litsales@rc.org>. Thank you!
