Meadowhall Shopping Centre in Sheffield was expecting today to be the busiest day of the year after bargain-hunters queued from 2am.
Meadowhall director Darren Pearce said it could be "our busiest Boxing Day to date."
Boy Bands Union J and The Vamps will be entertaining crowds of up to 15,000 at the Meadowhall shopping centre in Sheffield tonight - in the run-up to the switch-on of the mall's Christmas lights. The sell-out charity event is ticket only.
Anger has grown over Sheffield's attempts to have the station for the proposed high speed rail moved to the city's centre.
Neighbouring authorities and transport chiefs in South Yorkshire are angry that Sheffield is trying to force the Government to re-think plans to site the HS2 station at Meadowhall.
Today, HS2 bosses came to Yorkshire to listen to the arguments about the location. Our reporter David Hirst has been looking at why there's been such a difference of opinion.
The new high speed rail line HS2 could damage our region's economy. That is according to a report by MPs today, who say a fast rail link between London and Leeds via South Yorkshire, could mean economic activity being sucked down south.
The government says that's nonsense, and insists the line will be built. Phil Hornby reports
Margaret Hodge MP, Chair of the Committee of Public Accounts, has said the economic justification for HS2 is "very questionable".
It comes as the Committee of Public Accounts issued a withering assessment of the HS2 high-speed rail project, warning costs were spiralling whilst benefits were dwindling.
The Transport Secretary, Patrick McLoughlin, said the case for the £50 billion project was "absolutely clear," as rail routes would be "overwhelmed" by rising passenger numbers.
MPs from the Commons public accounts committee have called for the Department of Transport to provide more detailed evidence to support the estimated £50 billion investment. Presenting the committee's findings, chairperson Marget Hodge said:
The pattern so far has been for costs to spiral - from more than £16 billion to £21 billion plus for phase one - and the estimated benefits to dwindle.
In my committee's experience, not allowing enough time for preparation undermines projects from the start.
Transport Secretary Patrick McLoughlin has rejected the findings of the Commons public accounts committee, which criticised the costs and benefits of the HS2 high-speed rail network.
Mr McLoughlin said the case for the £50 billion project was "absolutely clear," as rail routes would be "overwhelmed" by rising passenger numbers. He said:
"The project will free up vital space on our railways for passengers and freight, generate hundreds of thousands of jobs and deliver better connections between our towns and cities.
"HS2 is a vital part of our plan to give Britain the transport infrastructure it needs to compete.
The HS2 high-speed rail project has come under renewed attack by the Commons public accounts committee, who have accused the Department of Transport of failing to present a "convincing strategic case" for the £50 billion project.
The public spending watchdog raised a number of questions about the apparent benefits and warned the costs were spiralling.
