Woolworths is promoting its clearance (paper-wrapped) 250g 'special variety' lines at my local, at aisle-ends.
Examples exclude the standard Dairy Milk variety (now 200g, in box), but include Caramello 250g, Marble 250g (milk & white choc blend w. hazelnut praline) and others.
Was $4.97, now $2.99, save $1.98.
(Not as good as the 250g block for $1.99 mentioned previously, but best of the rest in Sydney).
Edit to add
Previous deal, $1.99:

Is there a reason for the blocks to be downsized by 20% besides corporate greed?
