The Federal Competition and Consumer Protection Commission (FCCPC) has sealed 4U Supermarket in Abuja.
It was sealed on Thursday over unfair practices by its management.
FCCPC officials took the action during an enforcement exercise in parts of the nation’s capital.
The move is a direct response to concerns raised by consumers about the rising costs of goods which go against the recent strengthening of the naira against major currencies.
The Commission said price discrepancies remain a significant issue.
