INCORRECT PRICES

I have yet to shop from any Checkers where the prices on the specials ring up correctly. I always check my slip ,because you cannot see the discount on the specials (Would be great if they showed as they rang them up). The system should be open and transparent. Wasted too much of my time at Checkers waiting for a person to come make the correction. And I bet they do not correct each error that is made, and that the next unsuspecting client will also get the incorrect price. So disappointing that a shop of this size can not get it right!
