单选题 Tuangou, also called team buying or group buying, is a recently developed shopping strategy starting in China. Several people connect over the Internet and agree to contact a seller of a specific product so that they can buy the same item as a group at a lower price. And the sellers benefit by selling many products at once.
When people agree on group buying, individual members of the buying group can vouch for (替……担保) a particular seller"s quality to the rest of the group, therefore Tuangou helps change a traditional distrust of goods purchased from unknown sellers. Similar phenomena exist in Europe and North America. However, most of the group buying in these places is organized and done not by the team members themselves, but through online go-betweens.
