The Fiji Commerce Commission is threatening shopkeepers with jail if they refuse to stock certain items or charge prices above the recommended level.
The Commission's chairman, Mahendra Reddy, says police and military officers will check supermarkets on Saturday to ensure they comply with last week's Commission order to lower prices of about 20 commodities.
This comes as several shops defied the instructions, with some refusing to stock items such as powdered milk and lamb chops because they would have had to sell them at a loss.
The Commission's chairman, Mahendra Reddy, says those found to have prices above the recommended retail price will be fined 1,600 US dollars on the spot.
He says supermarkets found to be holding back stock and not putting them up on the shelves are liable to fines of up to 14,000 US dollars and imprisonment.
