Black Friday 2026: How to Tell a Real Cut From a RRP Repaint Before You Click

Black Friday 2026 lands on Friday 27 November, with Cyber Monday on the 30th. That's still three weeks away, which is why your inbox is already full of 'early Black Friday' badges and your local retail park has a banner up that looks like it was printed in a hurry. Some of those cuts are real. A fair few are the January sale wearing a novelty hat.

Nobody is going to hand you a list of the honest ones, so here's how to work it out yourself in about five minutes per item.

Who's actually blinking first

The early movers this year are the usual suspects: Currys, Argos, Amazon, Very, Boots, Dunelm, and the Sports Direct and JD stable. Electricals and beauty gift sets tend to lead because they're the categories that carry the biggest margins and the most leftover stock. Home and furniture retailers follow in mid-November, once they've seen what hasn't shifted.

What that means practically: the biggest percentage discounts in the first fortnight are almost never on the thing you actually wanted. They're on the thing the retailer ordered too much of in September.

The 28-day rule, and why it's your best weapon

Under UK pricing guidance, a 'was' or 'now' comparison price should generally have been charged for 28 consecutive days in the previous six months. That single sentence is the whole game. If a retailer says 'was £149.99' and the item actually sat at £149.99 for eleven days in March before dropping to £119 and staying there, the comparison is doing a lot of unpaid work.

You can't always prove it. You can almost always smell it. A discount of 55% or higher on a mid-range product that nobody else has ever sold at full price is usually theatre.

Five minutes of homework per item

• Amazon: run the listing through camelcamelcamel or Keepa and look at the twelve-month graph, not the thirty-day one. The thirty-day graph is where the fake markdowns live.
• Everything else: PriceSpy and Idealo cover most UK electricals and household names, and both show historical prices rather than only today's.
• Google Shopping: price insights give you a rough sense of whether a number is normal for that category.
• HotUKDeals: search the product name and retailer. If the community has priced it before, they'll have said so bluntly — sometimes rudely, but accurately.
• Your own screenshots: photograph or screenshot the price today, 7 November. Whatever happens on the 27th, you'll have your own baseline instead of the retailer's.

The four tells of RRP theatre

1. The full price nobody ever paid. A recommended retail price isn't a price, it's a suggestion the manufacturer makes so shops have something to cross out. If the only place a product ever sold at £199 was the manufacturer's own website for three weeks in 2024, it isn't a real £199.

2. The bundle shuffle. 'Save £120' usually means the headline discount has been redistributed into a free case, a two-year warranty and next-day delivery you didn't ask for. Price the item on its own before you accept the bundle.

3. 'Lowest price ever' with no date range. Lowest in the last week is not the same as lowest in the last year. If the claim has no window on it, assume the window is tiny and embarrassing.

4. The multi-buy that maths badly. Three for two on a product that's been permanently reduced to 70% of its original price for six months is not a saving. It's a nudge to buy three of something you needed one of.

Where the genuine cuts tend to hide

• End-of-line tech. Last year's model, still perfectly good, discounted because the box has changed colour. This is the most reliable Black Friday saving there is.
• Big appliances with manufacturer cashback stacked on top. Check whether the cashback claim window closes before you can realistically install the thing.
• Beauty gift sets, but only if you do the price-per-millilitre against the full-size product. Some sets are a steal; some are a travel-size bottle with a bow on it.
• Winter clothing in mid-season, especially at chains sitting on too much stock after a mild autumn.
• Subscriptions and memberships, which are genuinely discounted and genuinely renew at full price twelve months later. Diary it.

The bits that trip people up

Check the returns window before you buy. Many retailers extend Christmas returns to January, but the extension usually only applies to purchases made after a certain date — and a Black Friday order can fall on the wrong side of it. Check delivery dates against when you actually need the item, not when the retailer says it'll dispatch. And if a deal is only available by signing up to a credit agreement, that's not a bargain, that's a finance product with a discount attached.

One honest comparison

For televisions, large appliances and anything with a model number, January is frequently cheaper than November. Black Friday's advantage is stock certainty, not always price. If you can wait six weeks and you don't need the exact model, waiting is often the smarter financial move — and the shops know it, which is why the urgency messaging ramps up towards the 27th.

The short version

Screenshot prices this week. Set alerts instead of browsing. Check the twelve-month graph, not the badge. Treat any discount over 50% on a mid-priced item as a claim to be verified, not a gift. And remember that the best Black Friday purchase is the one you'd have made in February at full price anyway — everything else is a shop paying you to take its problem stock off the shelf.
