Black Friday originated in the USA in 1950s/1960s and takes place on the Friday after Thanksgiving.
Black Friday was brought over to the UK by Asda in 2010, part of the Walmart group.
However in 2015 the supermarket didn't take part in the event and it hasn't been confirmed if they will be launching any Black Friday sales in 2016.
In 2015 the average spend instore was £41 while the average amount spent my customers online was £92.
On Black Friday in 2015 £1.1 billion was spent and there was £3.3 billion spent over the weekend as a whole, including Cyber Monday.
A staggering 1.4 million people went into debt as a result of their spending on Black Friday in 2015.
When surveyed, 22% of Brits admitted to having bought something on Black Friday through the years.
