OK, my brother and I have always done flyers. But I feel the effectiveness of them has gone way down. So next spring I want to try out Direct Mail. So my question is, where can I find a mailing list that is not too expensive? Also, when I get the list, do I take that to the post office or what? I know there are companies that will send out postcards and whatnot, but what is the most cost-efficient method?
