So I started putting return address labels on the package inside the envelope, as well as the envelope as well obviously. The idea is, if the envelope gets destroyed and they just have this random little envelope sized package of cardboard, hopefully they see the return address label on it, and can get it back to me, then I can resend it. Figured I have PLENTY of return address labels since as we all know, if you make one donation to any number of charities, you get return address labels from them for life!
