In recent times, group buying websites such as Pinduoduo in China and Teamkaro in India have emerged in the online shopping business. Typically, these websites feature a "deal of the day", with the deal kicking in when a set number of people agree to buy the product or service. Buyers then print off a voucher to claim their discount at the retailer. Many of the group-buying sites work by negotiating deals with local merchants and promising to deliver a higher foot count in exchange for better prices.
