Bad Attitude

Good day, I went down to my local Pick 'n Pay today, and while I was in the luxuries aisle I saw a birthday notice displayed, saying any 3 packs of Lays chips for Thirty Rand. It was not limited to any variant or size, so I thought well it's a bargain if I take 3 party packs. <br> At the till it was a different story, and all the manager could say was sorry, but I had to pay the full scanned price of R19,99 each. I paid the full price and went back to the aisle, to photograph this unjust practise, and low and behold the sign is being removed to eliminate any further \embarrassment"(losses) to Pick 'n Pay. <br> I would like this to be resolved"
