Incorrect pricing

Good day. My wife and me normally shop at Makro Centurion, where they seem to have their barcodes and till pricing sorted out. This past Saturday, 1 August, my wife and me were in Edenvale and decided to shop there. I normally record the prices as reflected on the shelf by the shelf talkers. When we came to the till, 4 items had incorrect pricing. 100 Ml Colgate Toothpaste (12 pack) was R103.95 at the till but R86.95 at the shelf
