Kedai runcit or sundry shops have been a standard feature of our housing estate landscape ever
since there were housing estates. These mom-and-pop operations have been selling to their
surrounding residents everyday essentials such as groceries, fresh produce, poultry, toiletries,
etc. Their reasonable price and close distance have made them popular among residents of the
housing estates in which they are located. Lately, though, their popularity has been on the decline
due to competition from wholesale markets or hypermarkets which can offer the same items
cheaper and conveniently under one roof. Local and foreign-bred hypermarkets such as Giants,
Tesco and Carrefour have been invading our towns, big and small, leaving the traditional sundry
shops fighting for their business. Many of these small-scale individually-owned shops have since
closed their operations permanently or moved them a little further outskirt of town, away from the
hypermarket catchment. Just how serious is the impact of these hypermarkets on the operation of
the sundry shops has so far not been fully investigated in Malaysia although many studies have
been carried out elsewhere. Thus, this paper presents a study that has been carried out by the
authors to investigate how serious the impact is in Johor Bahru. A sample of three hypermarkets
was chosen for this study. Using GIS, we spatially showed the annual changes in the density of
sundry shop licenses issued by the local authority within the catchment of each hypermarket,
three years before as well as three years after the inaugural date of the hypermarket. Also using
GIS, we corroborated the decline in the number of sundry shops within the surrounding housing
estates with the residing addresses of the surveyed customers of the hypermarkets. The results
obtained confirmed that the operation of hypermarkets does contribute to the decline in the
number of sundry shops and the degree of the decline decreases radially outward from the
location of the hypermarkets. The findings from this study suggest that some rethinking needs to
be done about the manner in which hypermarket licenses, or sundry shop licenses for that matter,
are issued. Even our current policy of allowing a certain percentage of new housing development
to be set aside for shoplots may also need to be reviewed
