Consumer watchdog Which? has revealed that it intends to sue JJB Sports on behalf of people who were unlawfully charged for replica football kits.
The legal action relates to the sports retailer being one of seven companies fined by the Office of Fair Trading four years ago for its role in fixing prices of England and Manchester United football shirts in 2000 and 2001.
But Which? says that the £6.7 million government fine is little consolation for those consumers who were overcharged and as such is seeking action for damages to force the retailer to reimburse affected customers.
The consumer magazine's editor Malcolm Coles today said that he wanted to hear from anyone who bought the shirts in question during the two-year period, regardless of whether they still had receipts.
"We hope it will soon be payback time for JJB Sports. They ripped off their customers, so we think it's only fair they should have to pay them back," he said.
"We can't promise a big payout, but we'll do all we can to get justice for consumers."
JJB Sports has two weeks to respond before Which? files the action at the Competition Appeals Tribunal.
A statement from the retailer said: "JJB Sports notes the Which? announcement that it intends to take legal action against JJB Sports for the sale of replica football shirts during the alleged price fixing of 2000-2001.
"JJB Sports is in consultation with its legal advisors and will make a formal response in due course."
