I was sooo sick of getting 10 new credit card offers a week, so I just opened them and write "stop sending me this sh1t" on the offer and put all of the crap (even their envelope that contained the offer) into their envelope and send it back to them in the postage paid envelope. I've called the 800 # that is supposed to stop the flow but that didn't help. I have noticed fewer and fewer tho since I've been doing this.
