Black Friday has become a shopping institution in the US, where it falls the day after the Thanksgiving public holiday and retailers slash their prices in a bid to get the Christmas shopping season started with a bang. And it's now getting bigger over here, led unsurprisingly by the US-owned retailers.
So who is taking part this year and what are they offering?
Amazon
Amazon brought the Black Friday concept to the UK four years ago and is running a week of deals from Monday 24th. It is promising big discounts on thousands of products including a Sony 48-inch TV and Xbox One bundles.
Argos
Argos promises a “huge sale” on products including tech, toys and TV. The event runs from 6am. At time of writing, the Argos website was limiting visitors due to the huge number of people trying to access the site.
Latest offers include iPad Air 16GB at £299 (down from £299), Tassimo by Bosch coffee machines at £39.99 (down from £99.99) and Dyson bagless cylinder vacuum cleaners at £149.99 (down from £249.99).
Asda
Asda is of course owned by American retail giant Walmart, and last year introduced in-store only discounts. the sale runs from 8am on Friday and run for two days at 441 stores.
Bargains it's trailing include 40-inch Polaroid LED TVs for £139, Samsung Galaxy Note 8-inch tablets for £149, Polaroid 10-inch tablets for £109, and Little Tikes activity tables for £20.
B&M
Just when you thought B&M couldn’t reduce its prices any further, it’s giving shoppers 10% off everything on Friday. It’s a quick one though as you’ve only got between 5pm and 10pm to get the discount!
Boots
Not content with just Black Friday, Boots will be launching deals across the whole weekend from Friday until Monday. There's 50% off a range of perfumes, including Elizabeth Taylor White Diamons and Boss Ma Vie, up to 60% off men's grooming products and discounts of up to 50% on kids toys.
Some deals are online only, while others are only available in store.

BT has a broadband package sale on until Monday, with Sainsbury's gift cards up to £100 on offer with certain deals.

Bag some cracking deals on a selection of the biggest games and consoles this Black Friday. There'll be offers running through the week in the build-up to the main event which Game says will "dazzle" customers. It starts at midnight on 28th November.
Halfords
After a successful Black Friday event last year, Halfords is bringing back its Black Friday sale with deals on “big-ticket products” such as bicycles, technology, audio equipment and sat navs.
John Lewis
The home of Monty the penguin puts it very simply: “If our competitors have a sale we have a sale”. To that end, it will be offering 100 deals online and in-store including electrical products like tablets, laptops and televisions.
Bargains spotted include iPad Minis 16GB for £149, Kenwood kMix Stand Mixers for £169.95 and Nokia Lumia 2520 tablets for £199.95.
Given John Lewis offers more generous guarantees than its competitors, it might be worth seeing if it will match a deal you've spotted elsewhere.
