The present invention provides a checkout system which comprises an item accumulation (bagging) area which is partitioned into two or more sections using a flexible divider. The flexible divider extends from the entry zone of the accumulation area to a point on the boundary of the accumulation zone, but is longer than required to achieve this. When items are introduced into one section of the bagging area, if the items push against the flexible divider, for example due to weight of numbers, the divider flexes into the other section thereby making more space available in the current section for the items. Optionally the flexible divider is movable between two positions in the entry zone such that it further acts as a diverter for diverting items into one or other of the two sections and preferably a motor is used to automatically perform the movement.
