Observant high street bargain hunters will know, however, that some stores are already offering decent discounts.
Laptops, washing machines, games consoles, mobile phones, furniture, toys and clothes are all expected to be up for grabs at a fraction of their usual price, which is excellent news for those aiming to purchase festive gifts in good time.
Super sales on sought-after products are always welcome, but this year they will be needed more than ever to help with the cost of Christmas as people struggle to make ends meet after a year when Covid-19 wrecked havoc on many lives through job losses and falling income.
Black Friday is a tradition that originated in America where retailers trying to get 'out of the red and into the black' slash prices on a huge selection of items the day after Thanksgiving - but the event has been fully embraced by the UK and is now an annual phenomenon here.
People can now expect major UK retailers to reduce prices on a large range of products including big budget electrical goods, tech, beauty, smart devices and kitchen equipment.
Many companies, such as Amazon, actually begin discounting from mid-November in a bid to stay ahead of competitors, so canny consumers should keep an eye out throughout the month.
And in recent years, Argos, Currys, Very and eBay have worked very hard to best Amazon's best prices and have become Black Friday favourites in their own right.
Cross-category retailers generally have the best deals on the most-wanted products, although there are exceptions.
It is still too soon to tell what exactly will be on offer on Black Friday 2020, but there are early indications of what we can expect from the big players.
Amazon generally offers tech deals and already there are bargains to be had. For example, the Oral-B Smartseries Black 6500 CrossAction Electric Toothbrush was £229.99 and now costs £59.99, while the Fitbit Inspire HR is down £30 from £89.99 to £59.99.
