NEW YORK - Watch out shoppers.

Only 33 percent of supermarkets in the city are following the law when it comes to pricing food accurately, according to a report by the Department of Consumer Affairs.

The DCA inspected 500 supermarkets citywide in 2010. The majority of the city's supermarkets use innacurate scanners, tax items that are not taxable such as medicine and milk and don't display prices.

Supermarkets who violate these consumer rules could face fines more than $310,000, according to the DCA.

Consumers who feel they are being overcharged should file a complaint with 311.
