Price controller

Checkers brentwood. I have been shopping @ pnp previously it's now checkers I shop here daily and have been monitoring prices on items of interest to me it's is absolutely a **** checkers is running as the now are in monopoly today a price states buy 2 for R32 in 2 days time the same items is on special again this time buy 2 for R34 .Shocker. Futher to this daily on items we purchase goes up everyday .How is this possible surely your suppliers are not increasing prices daily Your suplliers have contracts with you and increases are only in at certain intervals .Pick n Pay was doing the same thing we approached them and the answer was we can put up or drop prices as we feel and what's happening to them now.Checkers beware we monitoring you .
