Group–buying in China

Modeled after US hot website Groupon.com, group buying websites are now popular in China. These websites use the power of group buying to get competitive discounts (打折)for a daily deal on some best stuff to do, see, eat and buy in the cities across China. Discounts are available within just one click. Zhao lei, a software engineer in Beijing, loves the one-hour lunch break at noon, as it is the best time for him to check “today’s special” at his favorite group buying websites . Sometimes he searches for great deals at directory sites devoted to the new shopping space. Zhao spends around 800 yuan ($117.65) on group buying every month, mostly to buy food coupons (优惠劵)for eating at some nice restaurants and occasionally to find something fun to do. ‘‘I love group buying. In addition to the competitive discounts it offers, it helps me get something fun, exciting and new, and such surprises give me a reason to try something new,” he said. When he finds a really good bargain, he will send the link to friends or colleagues through MSN,QQ, or e-mail, or share the information at some social networking websites. In doing so, he often gets a certain cut off the price. At some sites, buyers are invited to leave notes about what they want to buy and the website will consider it if similar applications(申请)reach a certain number. That is how Zuo got her digital camera after waiting for two months. “It is cool. I want to buy a new digital camera for my trip to Switzerland this winter, but I never expected such chea p prices!”Zuo said.
