Britons are set to spend £4.7 billion online and on the high street in a post-Christmas spending spree, figures suggest.
Boxing Day sales will total £2.9 billion as four million shoppers descend on the high street while 1.4 million plan to shop online on Christmas Day, according to research by MoneySupermarket.com.
The poll of more than 2,000 consumers suggests 22.67 million will shop online for post-Christmas discounts, with a further 24.61 million planning visit the high street for the January sales. They are set to spend a total of £4.7 billion on discounted items.
Of the 1.4 million logging on during Christmas Day, searches are expected to peak between 1pm and 2pm, the poll found. Between December 27 and 31, 21% of consumers will visit the shops and another 16% will buy online. However a further 18% said they will wait until after January 1 to go to the high street sales, while 12% plan to shop online after the New Year celebrations.
MoneySupermarket.com personal finance spokeswoman Clare Francis said: "Bargain hunters who are really keen to get the most out of their sale spend are using the internet to search for the best deals as soon as they become available. Many online retailers are starting their traditional post-Christmas sales on December 23 this year.
"My advice is not to be drawn into headline offers. Use a shopping comparison website to make sure you really do get the best deal. Also, don't spend what you can't afford. Discounts may look attractive but consider whether you really need the item before parting with your hard earned cash. It's not a bargain if you don't need the item in the first place."
British Retail Consortium spokesman Richard Lim said: "It's no coincidence that the growth of online retail and the importance of post-Christmas sales have grown in recent years. Early indications suggest very strong online retail sales in December with shoppers ordering presents later than ever, the ease and convenience driving that growth.
"Shoppers are increasingly taking advantage of seasonal discounts from the comfort of their armchairs and, with a variety of tablet devices at the top of Christmas lists, it's no surprise nearly five million of us will be shopping online on Boxing Day.
"Although tablet penetration is still relatively low, our own figures show that around two in five retail related searches on mobile devices come from tablets. Last December saw a jump in the proportion of mobile-related retail queries as a result of Christmas gifts and the impact this year could be even more profound."
