Clothing and footwear are expected to attract the most spending at £2.1billion, followed by consumer electronics at £1.68billion and cosmetics at £870million.
Almost two-thirds of Britons, 63 per cent, see the event as a good opportunity to save, compared with 35 per cent last year. Almost 45 per cent of Black Friday shoppers plan to use the sales for Christmas purchases.
However, discounts should not encourage shoppers to buy things they do not need, Clair Hughes, savings expert at VoucherCodes.co.uk, warned.
Ms Hughes said: “The best way to avoid getting carried away is to plan ahead. Have a wishlist ready, and check the prices in the run up to Black Friday. That way, you’ll know whether you’re actually getting a good deal.
“If you’re looking for an easy hack to save even more in the sales, purchase a Discounted Gift Card through VoucherCodes.
“Costing less than its face value, these Gift Cards can usually be stacked on top of Black Friday discounts for extra savings in the sales.”
