We customers are NIT stupid. We DO notice a difference of pricing from goods at the shelf a d at the till!!!

Why the heck are prices on the shelves not the same as to pay at the till??? And why it always that the customer would have to fork out more a d it's never to DIS-CHEMS disadvantage?? Happened now 2 x in the past to me at Victory Park. Would appear that Retail/Pharmacie percieve customers as stupid To be fair, same ***x goes for Clicks.
