Going to the well too often?

How often is too often to receive solicitations from a non-profit? I'm asking, 'cause PP just sent me another solicitation. It's probably the third mailing I've received from them this month, plus the weekly emailed updates. Yes, I know bad things are going on in SD and with the Supremes and freedom of choice is being infringed upon everywhere in the US. But seriously, PP, you need to time your solicitations better. The check for my last donation just cleared, literally earlier this week, and yesterday there was another request for more money waiting in my mailbox. How much disposable income do you think I have?

This isn't just a PP thing. I get the same from NARAL and the ACLU...despite the fact that I stopped donating to the National ACLU organization after being verbally abused by a telephone solicitor for them a couple of years ago.

Does the return in donations make these bulk solicitations worth it? It must, or I wouldn't still be getting these letters in the mail.
