As the Chinese grassroots' self-proclaimed Singles' Day, which falls on November 11, gains popularity, the country's e-commerce websites have grasped the chance to make money. The burgeoning online retail website Tmall.com launched a 24-hour sales promotion beginning Nov. 11. By the end of 14:00 (0600 GMT) on Sunday, the transaction volume of Tmall.com and its consumer-to-consumer (C2C) counterpart Taobao.com has surpassed 10 billion RMB (about 1.6 billion U.S dollars), higher than the single day on-line sales volume record of the United States in 2011.
