The China Internet Network Information Center (CNNIC) has today released a paper entitled 2011 China Group Buy Users Investigative Report which paints a picture of the daily deals landscape in China – and the many dissatisfied users who buy the deals. In total, 42.2 million of China’s 500 million netizens have used group buy sites in the past year and an astonishing 45.6 percent of them have had negative experiences with what they’ve bought. Of course, that’s often an issue with vendors rather than with the deals sites themselves.
