Well, want to bankrupt a charity you don't agree with?
Donate about $20 to them.
Over the next year I'm sure they'll send you way more than that...address labels, drink coasters, calendars, bookmarks (socks for heaven sakes!) etc., etc. Heck, some even send you real currency---nickels, dimes, dollar bills and checks for $1.50. Figure in the office help, postage, paper, printing costs, envelopes etc. Well, I can't imagine what your $20 donation has cost the charity you donated to. Just a thought.
