GST impact on your grocery bill

India's biggest tax reform since Independence, the Goods and Services Tax (GST), rolled out past midnight on Friday in the Central Hall of Parliament has ushered in a new tax regime.
A minute after the stroke of midnight, President Pranab Mukherjee and Prime Minister Narendra Modi pressed the button to launch the new indirect tax regime on a digital screen with "GST" emblazoned on it in a golden hue.
