my lovely pharmacist at Boots Tottenham Court Road recommended that I got a Prescription Prepayment Certificate to cover my new prescription for 6 months supply of Elleste Duet (each month dosage charged as two prescriptions). I duly went online and applied for a PPC, paid £29.10. When I went to pick up my prescription today I walked away with 6 boxes of tablets (usual charge £18 per box) and I wasn't charged a penny. That can't be right can it?
