By chance I went to Dmart (I heard about it some time back when I was in Mumbai) near Kundanhalli gate. It was a month end. 30th of November 2013 to be exact.
I was amazed to see the discount offered on all the products, exceptionally good value for money.
I am now sure that the other supermarkets are actually looting people. Reach to Dmart, even if you stay 20km away from it. I am sure anyone can save 250-1000 Rs.on your monthly bill even after spending so much on your fuel cost.
