WOOLWORTHS ADVERTISING ON PACKAGING

I was shocked to see Woolworths try and do a 'sneakie' - thought this kind of thing was above them. I purchased a bag of candy that had a big sign on it saying NO SUGAR. That's good enough for me. Then my son arrived and picked up the packet and said 'but it says NO SUGAR - and underneath in the smallest print - 'added'. What does that even mean? Why would you do that Woolworths. Why not keep that entire message in the same font? What are you actually supposed to be achieving? And what are you saying?
