The state of Indian law

Generally the rule in India is that we no one should sell any material more than what is printed as Maximum Retail Price (MRP). But in the Asia’s biggest buss stand, Chennai Mofussil Bus Terminus (CMBT), the shopkeepers are selling all the items two rupees more than the MRP. This not only happens in CMBT, but it happens in many places in India. But there is a small difference. When I went to Delhi, in a tourist spot a shopkeeper sold an Aquafina water bottle two rupees more than MRP. When I enquired him about this, he tried to hide it by saying its VAT. But when I asked the same in CMBT, the shop keeper very boldly told that in CMBT all the items are two rupees more than MRP. Selling an item more than its MRP is against law in India. But in one of the place which belongs to govt, the shopkeepers are selling saying the reason very boldly. This is the present state of Indian law.
