This year Black Friday falls on 24 November in the UK, just four weeks before Christmas.
We've created a handy guide for you below to find out all you need to know about this year's big day.
What is Black Friday?
Black Friday is the biggest discount shopping day in the lead up to Christmas. It's not restricted to instore discounts either, plenty of retailers offer significant deals online as well.
While the shopping extravaganza used to be confined to the Friday alone, in recent years we've seen deals popping up throughout the week leading up to the big day.
Where did Black Friday come from?
The shopping event started in the US in the 1950s and 1960s and falls on the Friday after Thanksgiving. The American holiday happens on the fourth Thursday of November each year.
While it may have originated across the pond the phenomenon took hold in the UK as recently at 2014. Although it hasn't been a fixture of the shopping calendar in the UK for that long, it has really taken hold in the last three years.
What happened on Black Friday 2016?
However this wasn't just restricted to the £1.23 billion spent on the Friday - IMRG estimated that around £6.5 billion was spent over the course of the week. John Lewis alone posted its best ever weekly revenue of almost £200 million last year after Black Friday.
Astoundingly it was also reported that Barclays processed nearly half of all payments made in the UK last year.
