I have a very anecdotal example let's take price of FMFL in IT cities of 3 different states - NCR, Pune, BangaloreBut I have heard similar stories from people in other metro cities now a days. So I believe all T1 cities(atleast) have been impacted by this, different scale maybe
Everyone knows that NCR is the cheapest, equivalent product in MH is 50% higher than NCR which is I think a fair price considering purchasing power of IT people and all the old money in Slumbai and Pune now here in comes the funny part wherein the same product is priced over 50% higher in Karnataka when compared to Maharastra price.
So as a pseudo bootlegger I can go to Delhi buy 6 bottles of FMFL in L1 and then come to Bangalore and sell at 20-30% cheaper rate than available in the market.
