Thanks for ur repliesDear Sir
for this purpose ull have to practically visit the retail stores and just observe which product like their u have and for what price it is kept there. then ull have to meet the marketing manager of the company and held a discussion showing the benefits of ur product as per the quality, price, supply etc. if u are better then the other competitor naturally the companies will prefer to keep ur product.
if its a new product then too ull have to explain the usefulness of ur product and convince them. u may start it with safal market
