The participants in this study may possess
attributes and behaviors that differ from those in other parts of the world. In addition,
the sample is skewed to a particular gender with 68 per cent of the respondents being
male, which may not exactly reflect the current composite of online customers. In
addition, it was impossible to send follow-up surveys and, thus, no attempt was made to
ascertain the existence of non-response bias by comparing responses from the
first-round surveys with a second-phase investigation.
