I did a search and couldn't find reference to this so apologies if it has been posted before. In any event this might be a useful reminder to those not aware. I read about this service some time ago on MSE.
If you are paying for more than one prescription per month then you can save money by purchasing an NHS Prepayment Certificate (PPC). A 4 month PPC is £34.65 and a 12 month PPC £95.30. You won't save money if you only have to buy one prescription per month at £6.65 but if you have to buy two or more prescriptions every month then this can be quite a saver. For instance my two prescriptions per month would cost £159.60 per annum and so buying a 12 month PPC saved me £64.30 - not to be sneezed at (pun intended) if you're not in the free-prescription category.
Couldn't readily find the NHS logo to paste so if a mod could do that please?
