International tourists were among the thousands hitting the high streets for today's Boxing Day sales, with retail experts saying foreign nationals spend on average four times more than domestic shoppers.
While shoppers from Qatar spend the most per transaction - on average £1714, tax-free shopping company Global Blue said Chinese shoppers were more likely to return to the tills with more goods at an average of £1,367 a pop.
Sue West, retail director at Selfridges, said the Boxing Day sales are very important for its international customers.
"The Chinese market is hugely important to Selfridges. It's one of the fastest growing international markets that we have," she said.
Chinese couple Wang Tianyi, 21, and Sun Yeting, also 21, were queueing outside Selfridges on Oxford Street in Central London from 4am and planned to head straight for the luxury items.
Christmas 2013 has consistently outperformed 2012 on virtually every single shopping day this December, with online visits from Christmas Eve through to Boxing Day up from last year, a record breaking Cyber Monday and the emergence of the even busier Middle Cyber Monday.
Shopping habits are changing, with Christmas Day becoming a significant shopping day during the period.
As a result, we anticipate a more sustained shopping pattern during this period, moving away from the traditional peaks and troughs usually evident during holiday season.
