The primary aim of this study is to examine the factors that influence Sacco members in Kenya to seek financial products from other financial service providers. The study investigated the factors that make Sacco members to seek the services of other financial service providers. Saccos are saving and credit co-operatives societies. Saccos are quasi financial institutions that mobilize savings, provide loans as well as other products to their members. To achieve this objective, the study employed the survey involving a sample of 100 Sacco members drawn from 18,833 members of the 44 Saccos operating within Central Rift Valley Region of the cooperative society. Stratified Random sampling was used to select respondents and a questionnaire was used to collect data from Sacco members. Both descriptive and inferential statistics were used to analyze the data. Hypotheses were tested using correlation analysis and regression analysis. Correlation analysis tested the relationship between the independent variables and the dependent variable while regression analysis was used to determine the contribution of each independent variable to the dependent variable. The findings of the study revealed that a large number of Sacco members took loans offered at the Saccos in spite of the cut throat competition by other financial institutions and that the Saccos were not as competitive as other financial service providers in terms of processing and delivering of financial products, the type of products offered and customer relations .
