The primary determinant of a potential customer's choice to acquire a good or service is its pricing. Retailers must take into account elements like manufacturing and operating expenses, sales targets, and competitive pricing.

This paper aims to study the different forms of price parity being practised by e-commerce players and how the statute provides protection and promotion of healthy competition.
