Yeah dump the flyers and knock the door, keep a record of the ones out so you can go back on them another time and get as many business cards out even to the ones who have a windy allready, just say. May i leave you my card incase your circumstances change. Its suprising how many ppl keep those cards incase their windy gives up or gets the sack. People like to see a face and hear a voice rather than pick up a phone blindly
