Unfair pricing

I am utterly disgusted and disappointed in what used to be my favourite retailer. I recently was surprised that they stock my brand of Parmalat lactose free milk. For the past month I've been purchasing 3 cartons a week. Today the price has been hiked up by R2.00 while the price of regular Parmalat milk has gone down by R1. This pricing discrepancy discriminates on people with medical conditions and who cannot tolerate lactose. It may be a small thing to you but it makes a hell of a difference in quality of my life. Shame you and your greed Pick and Pay.
