India is a different country, a different culture. It functions differently. This applies to every aspect of social activity, including how commerce is done. To someone who is visiting India for the first, one of the most striking features of an Indian bazaar, if they are not bedazzled by the immense crowds, is the constant negotiation over price. Rarely a deal is done in India that does not involve bargaining. It is not merely a cultural trait; there are some practical reasons too.
