STACKERS VS PRINGLES

I have always purchased Woolworths Stackers as they were like the old Pringles years ago when they first came to SA. However, I purchased 2 today and could not believe that the container was not full to the top and the size of the stackers (from Woolworths) are the same size as the new Pringles which are half the width of the container. Really disappointed in Woolworths because I did not believe that they would drop to the level of the Pringles product. They are more expensive than Pringles but now it is not worth the extra R10 for Woolworths product.
