Pick n Pay is TRASH!!!

Tried to purchase Cantu hair products as they had it at R100 for 5 items, as I am waiting for the casher to scan everything I noticed the products scanned for R100 each. I requested for a Supervisor who also doesn't seem to know what is on special she refers to the catalog which confirmed the special. She then went to call Gary the manager who straight us said "he cannot give it to me at that price as it was a printing error(that I did not make). We asked WHY was the products than still on the shelf, he could not answer and walked away.
