Prices is a *******

I landed up in hospital as a result of a serious iron deficiency. Had to receive blood and my Dr prescribed ferrimed. I ran out of Ferrimed and made a stop at Ridderspark pharmacy, part of the Arrie Nel group. Where I normally pay R300 for the ferrimed they charged R453 for exactly the same product and the same amount. Just how can this be justified?? We the public are dependent on these pharmacies and then this? The same product at Clicks is R390 also very expensive compared to dischem. Totally unacceptable and they will never see me or my family again.
