90% of prescriptions are free of charge.
A completely anecdotal experience which suggests this is true -
I once went in to get a prescription after work, so must have been around 5:30 and they had a trainee behind the desk who didn't seem to understand the concept of paying for a prescription. She kept saying 'you need to sign there!' (the exemption declaration) and I was saying, 'no I don't!' (unless I want to get done for fraud).
Not blaming her at all, as we all have to go through training when we start a new job but I was amazed that, at the end of a working day, she obviously hadn't yet had anyone else pay for a prescription.
