Savvy shoppers and deal hunters are expected to spend an incredible £4 billion between Black Friday and Cyber Monday this coming weekend.
Black Friday alone will see spending over over £1.3bn - up on last year’s £1.1bn.
Overall sales are expected to soar 19 percent this year, according to website VoucherCodes.co.uk.
However, last week consumer group Which? warned that some 49 percent of last year’s Black Friday deals were actually cheaper in the months before.
And retailers were caught out claiming higher discounts on goods by fudging data used for comparisons.
Alex Neill, managing director of home and legal at Which? said: “As Black Friday and Cyber Monday approach, it’s important to do your research so you know your shopping rights before you buy, just in case you change your mind.”
It comes as discount website lovethesales.com said suggested retailers would slash prices further in a post-Brexit battle for attention.
Mark Solomon, founder of the website told the Daily Telegraph: “Post Brexit uncertainty has resulted in increased competition between retailers, reflected by more aggressive discounting of inventory. If this trend continues, this Black Friday weekend will be the biggest ever.”
But earlier figures suggested this year’s Black Friday event could be the last of its kind due to post-Brexit vote currency fluctuations.
Retail analysts told Huffington Post UK that big stores might next year offer more lower-quality products that bring assured profit than eye-catching deals on big name brands - or stop participating altogether.
