This year the orgy of consumerism known as Black Friday falls on the 27 November.
A heavily discounted shopping day we’ve inherited from the US, Black Friday falls the day after Thanksgiving and sees shoppers sharpen their elbows in hope of bagging bargains galore - though this year Asda has taken a controversial decision to step away from the fray.
Black Friday was confirmed as the biggest online shopping day of the year in the UK for the first time in 2014 – with consumers parting with a whopping £810m - far exceeding the predicted spend of £363m.
Time to spend, spend, spend
Black Friday is immediately followed by Cyber Monday, when further discounts will be offered and the frenzy is expected to continue.
Here is where and how to pick up your bargains this year:
On Friday, Tesco has announced it will shut 250 participating Tesco Extra shops at midnight and reopen them at 5am for the event. Store managers will be on the premises during the event to assist shoppers. Price reductions are expected on TVs, toys and consoles.
Following hectic scenes at branches of the Walmart-owned retailer last year, Asda has announced it will not take part in this year's shopping bonanza, saying "shopper fatigue" has set in.
The supermarket said shoppers were no longer as interested in "flash sales on big-ticket, non-essential items at Christmas". The move comes one year after shoppers were said to be acting like "animals" in "war-zone"-like scenes. Previously, the store opened at 8am on Friday and added a whole extra day.
Sainsbury's usually dedicates a special section in its stores to Black Friday deals, with in-store only offers this year. The supermarket has a geolocator tool on its website so that you can find shops near you taking part in Black Friday. Main, front-of-store deals on electrical household items will run from the 27th until the 29th, while stocks last. Additional non-food deals will be available from the 25th November until 1 December.
The Oxford Street shop will open an hour and a half early at 8.30am, and stay open late until 10pm. Any additional opening hours for other shops will be announced online. The store is promising to stand by its commitment to being Never Knowingly Undersold with its Black Friday web page.
GAME has a series of Black Friday 'countdown deals' online already, and will kick off still more deals at midnight on Thursday. It has a detailed guide to Black Friday opening times for individual stores on its website.
CURRYS PC WORLD
Currys PC World is expecting such a surge of interest on Black Friday it's inviting customers to register their interest weeks in advance. An online queueing system is in place and if you leave, you'll lose your place. Shoppers planning to visit stores on the day can reserve items online, and are reminded to get there early and to "bring plenty of coffee to keep you awake before the doors open." Shop opening times vary and can be found on the Black Friday Currys site.
Argos recommends registering for an online account ahead of the big day and advises that 3am-4am is the quietest and thus optimum time to snap up deals and beat the cyber rush. Physical opening times can be found here.
