When I first started out I was putting fliers in mailboxes. The # of calls I got was minimal but thats the only way I could afford to advertise and get customers,,especially since I was in a town where I did not know anybody. Long story short I got a call from the postal service one day and she said that one of the mail people took all of my fliers out (she told me the exact # I had put out) and that she would let it slide this time, but the next time I would get fined 37cents for each flier (it may have been 34cents, but whatever the postage rate was at the time) Therefore, I would not reccomend doing this.
