More than 500 possible cases of price gouging of gasoline and other essentials, including a $10 box of matches and a $7 loaf of bread, have been reported in New York before and after Hurricane Sandy. Reports are being investigated in New York City, the Hudson Valley and on Long Island by Attorney General Eric Schneiderman. More than 300 reports were made over the weekend and yesterday, and that total is rising.

Schneiderman said he’s investigating an increasing number of reports of spikes in prices for essential goods, including gasoline, food, bottled water, generators, batteries and flashlights. The probe can include sharp, unwarranted increases in the cost of prices by retailers including supermarkets, hardware stores, bodegas, delis, hotels and taxis, he said.
