Shanghai authorities are cracking down on price gouging for group buying and delivery services, which have become a lifeline for people during the lockdown and other COVID-19 control measures.The city's market watchdog has punished 192 people guilty of price gouging and cheating, primarily related to selling vegetables, since the virus began resurging in March, said Peng Wenhao, deputy director of the Shanghai Administration for Market Regulation.More than 30 price-violation cases have been publicized. Two outlets of supermarket chain Century Hualian, for instance, have been fined for charging high delivery fees for online orders. Chain restaurant Jindawan, in another case, raised its delivery fee to as much as 100 yuan (US$15.71) from eight yuan per order. Another supermarket was fined by falsely claiming its vegetables were part of "\\;supplies to Hong Kong."\\;
