Wrong display prices, in violation of consumer protection act

Consistently and almost without failure, every time I visit the Morningside branch, at least 1 item's display price scans through at a higher price. Last Wednesday, it was for cat pellets. Of course I complain and get the display price. I have complained about this numerous times both on hellopeter and in the branch, for several years! PnP responds on hellopeter that they would contact me, but they don't. I don't expect this to change, but it speaks to the brain drain evident in SA. Hanlon's razor: never attribute to malice what can be explained by stupidity.
