Depends on who your audience is and the age group.Find the better possible way to advertise my physiotherapy sessions to a targeted local audience
I would just print a shit ton of flyers and stick them on notice boards in shops, hospital, ask small town shops to place them in window, charity shop windows, leave them on notice board and a pile in local library, leave some hospital waiting room area, local GP surgery, ask your local pub if you can leave a few there.
Thats how I would hit it off line. Mix of 1/3 leaflets and A4 type ones for the window.
