Black Friday has come a long way since it arrived in Britain in 2010. Once synonymous with hot-headed shoppers - thanks largely to an infamous bust-up in 2014 - the sales event has continued to expand, with most big retailers now participating.
An American import, Black Friday falls the day after Thanksgiving, with this year's event taking place on 24 November. Its popularity is no doubt partly because it falls so close to Christmas, allowing customers the chance to snap up presents on the cheap.
Last year was Tesco's biggest Black Friday yet. In a bid to compete with the likes of Currys PC World, Argos and John Lewis, the retailer had 11 days of slashed prices. Around 650 items were discounted, up from 200 the year before, and the sales were available at 700 stores as well as online. Expect even bigger this time round.

What deals can we expect?
Although it's too early to say exactly what will be on offer, last year's deals provide pointers - and it's much more than just groceries!
Some popular discounts included a NESCAFE Dolce Gusto Piccolo Manual Coffee Machine at £39, down from £79.50, a Sharp 49'' Smart LED television for £199, down from £329, and the Tefal Health Fryer's price was drastically reduced, from £149 to £49.
So whether you are after kitchen or home appliances, tech or health and beauty, Tesco should be high on your list this Black Friday.
How to choose the right equipment
Tesco has become a big player in the technology market, but it's not always easy to find the appropriate gear, particularly if shopping online. Here's some tips to bear in mind.
Buying a TV is far from easy. With so many types on offer it's important to decipher the relevant language. We don't all know our OLEDs from our LEDs, the difference in quality between LED and plasma screens, or whether we should fork out the extra cash for a 4K or Ultra HD screen. Of course, make sure you buy one that fits, as TVs range dramatically in size.
Tesco stocks a massive range of kitchen appliances, from taps, extractors and scales to coffee machines, food processors and pans. They also sell a host of white goods.
It's always worth getting good quality appliances, you don't want your new gadgets dying within weeks. This often means parting ways with extra cash, so Black Friday is a great chance to buy top products at a fraction of their regular price.
Impulse buys are tough to avoid on Black Friday, but consider what you really need. If buying online, make sure to check the measurements and aesthetics of the product. You don't want an oversized fridge or a garish item ruining your kitchen.
How to make the most of Black Friday
While Black Friday sees outlets across the nation slash prices across a range of products, there are several ways to make the most of your shopping experience. Savvy shoppers can even make further savings. Every little does indeed help.
A key piece of advice is to remain prudent, resist temptation and plan ahead. If you badly need a new TV or electric shaver, for example, wait for a deal in those fields. With so many items on offer it's all too easy to add unnecessary items to your basket, whether in-store or online. If you're not careful you'll rack up a pretty hefty bill -don't blow your budget too quickly.
Secondly, start looking early. Black Friday deals are often introduced in the week preceding the main event. You may find something before others if you're well prepared. Expect deals from mid-November.
With timing a crucial aspect of Black Friday deals can quickly sell out, so following Tesco's various social media pages can give you an extra boost in discovering the right discounts for you.
