For a retailer with an offline store the most appropriate marketing activity is the traditional style of promoting the business. First is the word of mouth that you can urge the present customers to help you in spreading the news. One trick is the referral system where the customer gets a sort of commission when he refers a client. Second is the use of posters and tarpaulins. Another way is the motorcade to announce the launching of the business although this is for big businesses only.
