Different store and different pricing!

Being buying ready roasted chicken for days at Checkers in Century City @R39.99/kg and today want to buy at Checkers Kloof St @R72.90/kg...spoke to management who told me that it is due to supply n demand n stock which is kept! What a load of hogwash!!! You are daylight robbing people because they have a different street address! Charging practically double the price! Sort yourselves out as I will not be stopping here with your thievery ****s! Enough is enough in this day n age!
