Yes, you pegged how I felt when I got my first full-size envelop from C4L in the mail. I thought it was an oddity (lengthy, writing style), but the second and the third were exactly the same. I think I stuck with them through number 5. Those have to be pricey to mail, which, I suppose, means a healthy chunk of any donations I've made has gone right back into attempts to wrench more money from me.
I will try to craft a response to C4L that isn't just a rant. Thanks for encouraging me to be thoughtful and hopeful.
