[Resolved]  Amul Dairy — Black Marketing

Today, I went to buy a packet of 100gm amul butter, and the shopkeeper had given me a chocolate with it,
i asked him whether it si free with amul? He said no, if you have to buy a butter cake then it is only available with this chocolate, only packet of butter is not available.He said that its company policy, I can't do anything.
Its the exploitation of middle class people.

I want clarification on it.Its the straight case of black marketing.
