Misleading Prices

I went to Pick n Pay Menlyn on Monday and close to the express tills there were DVD's on the stand. the one side of the stand showed 3 for R100 and the other side 2 for R100 engraved on each side of the stand. I took 3 Barbie DVD's from the side that showed 3 For R100 expecting to pay R100 for all 3. I bought groceries as well and did not notice that I was charged R49 for each which is R147 for the 3. I later checked my slip and went back to query in store and was told it has to state on the cover and should not look the stand. why mislead customers placing them on a stand that shows R100 for 3 and the other side of the stand showing R100 for 2. I even made sure that I took from the one side as the other side was R100 for 2. this is really bad service as I thought I would pay R100 for 3 and not R147 for 3. overall service is great accept for this one time where I was mislead. Disappointed
