As I have a government concession card for prescriptions (so no need for shopping around for most meds, but that certainly pays off in Aus too for most people)

I get all my meds from the closest pharmacy to me, at the local shops about 10 minutes walk from my flat. By law my Ritalin script must be kept at the same pharmacy and I am not allowed access to it. I have to pick it the months supply up on 'exactly' the 30th day since I last picked up my script. It is what they call a 'Schedule 8' drug here - no mailing allowed.
