However, the potential benefits of the product have not been fully exploited due to many problems including ineffective marketing techniques. In an attempt to address this problem, some organisations have facilitated the producers of kola to embark on group sales as a means to improve their marketing performance. During the 1st 5 years of implementation of this programme, there was no clear picture about the impact of the marketing intervention programme on the marketing performance of the farmers. This study discusses the main antecedents and producers’ perception of the effects of the group sales on the supply chain performance of kola producers in Cameroon. Using open ended interviews with 50 farmers, the study reveals that group sales has the potential to improve kola supply chain performance through increase in prices, quantity harvested and sold and increase in number of producers involved in the group.
