check your prices before buying anywhere

Before buying anything from Sasol or any foodcourt from any garage it would be advisable to check the price first. I just bought a 2 lt coke and a pkt of cigarettes for my wife and it cost me R84.50 It is shocking to see how companies can see the right to overcharge. Sasol is not the only foodcourt, other garages are on the same wave length compared to PNP and Checkers who charge reasonable prices for same items I have asked the person to reverse the costs for these items but I was told he was not allowed to do so.
