Millions of shoppers swamped Boxing Day sales across the UK as festive retail records looked set to tumble.
Many bargain hunters queued overnight to pick up the best deals on a day where shoppers were expected to spend almost £3 billion.
The UK average footfall was up by 21.6% on Boxing Day last year, the retailers' body said.
Manchester's Trafford Centre enjoyed what is thought to be the biggest Boxing Day sale in its history with police drafted in to help manage the crowds.
Meanwhile, several hundred thousand customers passed through London's retail mecca of Oxford Street, with shoppers from across the country joined by thousands of tourists, many from China.
ITV News' Matthew Taylor reports:
Sue West, Selfridges director of operations, said handbags and menswear were flying off the shelves at their flagship West End store. She said:
Scenes of shopping mayhem in London were replicated across the country.
At Birmingham's Bullring Shopping Centre, thousands were ready and waiting from 12:20am for the off. Some 350,000 passed through after doors opened.
Popular picks included the Next Boxing Day Sale, which started at 6:00am in many stores across the country.
As crowds swarmed the centre, Tim Walley, Bullring general manager, said:
In Bristol, hundreds of people queued from the early hours of this morning to be among the first through the doors of Cabot Circus' Next store.
Centre director Kevin Duffy said:
Twenty-thousand shoppers had arrived at Manchester's Trafford Centre by 8am, said Gordon McKinnon, director of operations.
At Kent's Bluewater shopping centre, queues began to form at 1am with more than 3,000 waiting at 7am.
Robert Goodman, Bluewater's general manager, said: "This is certainly one of the busiest starts ever at Bluewater for the Boxing Day sales."
Chinese shoppers have proven to be the top spenders as footfall rose 31.3% from last year in London's West End, with Middle Eastern and Nigerian shoppers also understood to be among the strongest growth nationalities at the tills.
The international shoppers were being greeted by a retail staff who spoke more than 22 languages combined, including Mandarin.
