Pick n Pay on Nicol sushi price manipulation

The sushi bar in Pick n Pay on Nicol has a Wednesday sit-in special that offers 50% off all colour plates. On any other day for sit in, the black plates are R54 per portion however on Wednesday only, the black plate price increases to R99 per portion. As a regular shopper, I know the prices and the 50% promotion is a ****. On Fridays, the takeaway special is buy any two 8/10 pieces and get the second one at 50%. Again the salmon sashimi is normally R64 on other days and on Fridays it increases to R74 (15%) which effective means that you not receiving the true 50% discount. Pick n Pay - I SEE YOU ;you don't fool me and I find this practice dishonest
