Black Friday has a way of making £180 look like a bargain because the label says it was £260 last Tuesday. Sometimes that is a genuine saving. Often it is the price the item quietly sold at in September, dressed up with a red sticker and a countdown clock. The only reliable way to tell the difference is to stop reading the discount and start reading the price history.
What follows is a checklist you can work through in the time it takes to make a cup of tea, plus a few habits that stop a Black Friday "bargain" becoming a January regret.
The "was" price is the number the retailer controls, so it deserves the most scepticism. UK consumer law requires a previous price to be genuine — the price the item actually sold at for a reasonable period before the promotion — but "reasonable" leaves room for interpretation.
Two practical conclusions follow. Treat every claimed percentage off as unverified until you have checked it. And pay attention to how long the higher price lasted: a figure that held from spring is a much stronger benchmark than one that appeared for a fortnight in October.
If you believe a price claim has misled you, complain to the retailer first, then take it further with Citizens Advice or your local trading standards team, who can point you to the right route.
You do not need a spreadsheet. Price-tracking tools keep charts of what an item has cost over months, which turns a guessing game into a quick glance.
A "Samsung 55-inch 4K TV" in one shop is often not the same set as the similarly named one next door. Retailers commission exclusive model numbers so products cannot be compared like for like, which also makes the "was" price almost impossible for you to verify. Search the full code — the string of letters and numbers after the brand name — before you decide you have found the cheapest deal.
Discounts tend to be real on outgoing tech: last year's televisions, headphones, tablets, smart speakers and fitness watches, where retailers are clearing stock. Broadband, mobile and streaming offers can also be worth taking, because providers compete for new customers regardless of the calendar.
Be more sceptical about newly released flagship phones and consoles, the year's most-wanted toys, and anything you had not planned to buy. In those categories, a discount is often an invitation to spend rather than an opportunity to save.
Write down two figures for anything you are seriously considering. Your target price is what you would happily pay today, based on the item's real recent history. Your walk-away price is the ceiling — the point at which you close the tab, however shiny the sticker.
That second number matters most. A purchase you did not plan for is not a saving; it is spending with a good story attached.
Check the price history. Confirm the model code. Add delivery to the total. Compare it with the target price you wrote down a week ago. If it still looks good, buy it and keep the confirmation email — you will want it if the price falls further or the item needs returning.
Use a credit card for anything costing £100 or more. Purchases from £100 up to £30,000 are covered by Section 75 of the Consumer Credit Act, which makes the card provider jointly liable if something goes wrong. Pay the retailer directly rather than through a third-party payment processor, or that protection may not apply, and note that debit cards offer a weaker chargeback scheme.
The best Black Friday deal is usually the one you were already going to buy, at a price you can verify. Everything else is just a red sticker.
