Ongoing frustration with missing prices on items at Pick n Pay

Why is it that PnP cannot price its goods properly? How is it that a retailer that has been around for so long is not able to keep the correct prices at the correct items? This has been going on for years and seems to be getting worse. Is is incompetence or a way to fop shoppers into purchasing good with higher prices? It has become a really disappointing and frustrating experience to shop at Pick n Pay. Get you act together!
