This table shows that an important grouping is missed in the three-cluster solution. Members of clusters 1 and 2 are largely drawn from cluster 3 in the three-cluster solution, and they are unlikely to be big spenders. However, members of cluster 1 are highly likely to purchase Internet-related services, which establishes them as a distinct and possibly profitable group.

Clusters 3 and 4 seem to correspond to clusters 1 and 2 from the three-cluster solution.
