I agree that groupon has the mind-share of investors in group discounts but there's lots of groupon like companies - think Amazon is pouring $175M into one of the clones, Living Social. So, I'm imagining the clones are growing in China as well.
Anyway, I am being too negative. The success of CCME's Groupon clone is dependent on the success of their SWITOW website. They have every chance of making it a success providing they can convert riders into buyers.
