Hi Holmans,
You could try counter display leaflet holders, and ask to put them in shops/clubs/associations/town hall etc,
or the post office do leaflet drops at the same time as delivering mail.
Personally if you have another batch printed in the future, i would get the printer to put different code numbers/lettering next to the phone number on different batches, and get the customer to quote this number for a discount,
that way you can get some idea of where your advertising is working best.
