I was looking for something along the lines of "South Africans spent R514-million on internet shopping in 2005, 20% more than in 2004, according to tech-watchers World Wide Worx ... and this excludes the R1.8-billion online airline sales contributed to domestic e-commerce in 2005."
Been to the World Wide Worx site and they offer the research for 2009 at the delicious price tag of R10 000. I was hoping the information from the 2008 or even 2007 report may already be in the public domain.
There is also the MasterCard survey http://www.southafrica.info/news/business/141975.htm
but the sample size is small and the research is tainted by the fact that it was conducted by the credit card company with questions about using a credit card (i.e I don't have the sample questions to decide if it was a reliable questionaire).
