Variety of products at a cheaper rate. Probably available in wholesale not sure about the retail. For bulk amounts this place is surely going to save a lot.
Rampuria Market is very nice market where A to Z is available with huge quantity. Here every thing is available. The market is always over crowded and very much congested. From other markets prices are cheaper. Here people from all over India come to market. Communication wise this market carries extra preferences because here bus, auto, taxi is always available. Howrah Station is nearby.
Very good market with a large variety of products available at very cheap price. Also, Vendors on the road side will sell you many products with brand names (but they are not actually original) at very cheap price. You need to know how to bragain specially with them XD. Rest of the market is very good to visit and buy. Genuine with good diversity of products you will find.
