Pricing

I went to buy some chocolates for somebody special coz I forgot her birthday. I get to Engen and find Ferrero Roche on the shelf marked for R88.50. I decide to take it, only to find out that when I get to the front, it scanned at R94.80. I call the manager hoping that she can put the pricing at R88.50. her response was that her guy on floor failed to change the pricing that she gave him the previous month. When I asked her to give it to me at that price, her response was that she cannot. I was so disappointed at the fact that I told her that it was her fault and not mine. Isn't it the price you see is the price you pay. So I left the chocolates and went somewhere else.
