Pricing of Salads

This is the second time it has happened to me, I think its Pick n Pay's way of making an extra buck along the line. I purchased a green salad today and was charged R70 per kg, it was charged under assorted salads. I have noted that a greek salads price is R32.99 a kg, I asked the lady who served me and she said its been like that ever since she started work there, Please could someone explain to me why there is no barcode (and pricing for a green salad which has a lot less items in) Greek salads have olives and feta cheese whilst a normal salad just has lettuce, tomato, onion and cucumber. I feel I have been cheated out of money and will no longer be buying salad from pick n pay but rather at Spar which has better value for money anyways.
