There was about fifty persons in this group . One day , instead of other subjects, their focus of discussion was Market Prices of Different Goods . During the discussion , the emphasis laid on the point was that goods become very costly by the time they reach the consumers after getting transported from the producers . Consequently , everyone's budget is getting disturbed . To get rid of this problem some people suggested that they should join together to form a society . The society would sell the goods to all the members as per their requirements after buying them in a large quantity directly from the producers . This suggestion was appreciated by all of them .
