SPAR Rosehill Mall pricing discrepancy.

Once again SPAR Rosehill Mall pricing in question. R13 discrepancy X +- 1000 customers = R 13 000 clean profit in the pocket PER DAY! This has been going on at SPAR for some time now. What a way to earn the trust of the community and deceive locals as well as holiday visitors! The manager's answer, we'll refund you which they did. How many costumers do not check and compare pricing to their till slip and walk out? System error? I doubt. GIGO
