My Mother used to save it all up for a couple of weeks, mix it all up, and stuff the envelopes with whatever was on the top of the pile. As mentioned the company does not get charged until the envelope is used.
As for the phone calls I love it when they call after a bad day at work. Gives me the chance to Vent off all that pent up anger without upsetting the wife or kids. I like to interupt their practiced speel constantly with "What are you trying to sell me".
I have also been known to sound off the personnal alarm into the receiver that one of the companies sent my wife in the post. They wear headsets remember, and I bet they can't get them off quick enough.
I'm not at all tolerant of this sort of thing. Strangely though, the Blonde jehovahs witless that turns up during Sunday dinner is always welcome.
