I am raising money for my birthday (April 22nd) so that one of my favorite Political organization "Grassroots Democratic HQ" can print postcards and buy stamps.  These postcards will then be made into packs of 25 postcards with stamps, addresses and script.   People (including me) will then drop these packs off to households to write out and mail.  $25 buys 50 postcards and stamps.

This is basically how I got 600 cards sent out for the special election in CA25.
