I dont know whats the quality difference between the chocolate they sell for Rs 10 and the one they sell for Rs 120. Both these chocolates taste exactly the same. So, in my opinion, Cadbury Dairy Milk Silk is quite overpriced as per its quality and quantity. And they also dont provide the aluminium foil wrappers that they used to pack the chocolate in earlier.
They should bring it back because it helps preserve the flavour of the chocolate.
