Tuseme amebuy 50kgs bag of sugar at 5,370 meaning a kilo imeingia na 107.4, after making a market survey unarealize other shops wanauza sukari kilo 140.Hassan anaweza set bei ya kilo ya sukari at 130 ,less 10 bob na other shops.This will give him a good room to compete and get more clients,the same can be done to other stock.Market survey,unacompare buying price Yako , what other shops are selling and set your selling prices lower na 5bob than them,this way, utapata high sales na pia a good profit
