I have a couple of experience in purchasing materials from Sansar, Kaggadasapura, and I realize that they were keeping a old and poor quality martials. The management and salesman's were not professional and they were un-ethical (beware of them), and they were cone you. Try to avoid this shop.
I am writing this revew because, I don't any other person go to the same unpleasant situation, which I faced last six months back.
