Robbing Clients

I was at the Checker's in York road in George on the 2.3.2020 and bought a carton of Rothman's mild. They charged me R399.90 for the carton which means they increased there cigarettes by R8 p/packet. when I was back in Cape town in the 3.3.2020 I queried the price of the same cigarettes at the N1 city branch and they charging R329.90. this I feel is highway *******. when I queried this with their customer service I was told it's because they using a different buyer and also because George falls in the eastern cape . This I feel is a stupid excuse and they robbing people
