The last marketer that came to my house was selling home security systems. I was a little upset because she woke me up from my sleep. She just didnt want to except NO for an answer. She was so presistant. Finally I said "Ok you know what, why don't you come in and lets take a bath together and talk about it". It was so funny. She told me to have a nice day and hasn't been back since! Give this one a shot when the next person knocks on your door trying to sell you something.
