Price Drop Timing: When Prices Fall in the UK

Prices in UK shops fall at predictable moments: the January sales, Black Friday, when a new model replaces an old one, and late in the day for fresh food. But none of these is reliably the cheapest point for every product. The best timing for a particular item depends on its category, its release cycle and its own price history. This guide explains the patterns, shows where they break down, and gives you a simple way to check whether a drop is real.

TL;DR

Big sale events (Black Friday in late November, the January sales) bring plenty of discounts, but Which? found that most sampled products were as cheap or cheaper at other times of year.
Older models of things like televisions usually get cheaper once new ranges arrive, so product cycles often matter more than the calendar.
Supermarket yellow stickers have no single UK-wide time; it varies by chain and by store.
Check a product’s price history over several months before trusting a “was” price.
If you paid more than the advertised price, you can ask for the difference or return the item for a refund.

Why prices move at all

Retail prices change constantly. A Bank of England study of UK consumer prices between 1996 and 2006 found that 19% changed in an average month, or 15% once sales were excluded. Goods changed more often than services: 24% a month against 9%. That data is old, and online pricing is faster today, but it makes the key point: a price is rarely fixed, so “waiting” is a real strategy.

Monthly UK price changes by category

Supermarkets move even faster. Weekly scanner data from February 2005 to February 2008 showed that roughly 40% of prices changed each week on an unweighted basis, and about 60% when weighted by spending.

Three forces sit behind most drops:

Stock and age. Shops reduce goods that are ageing, overstocked or about to be replaced.
Demand peaks. Retailers discount when many people are shopping anyway. Academic work by Warner and Barsky interprets markdowns as timed to periods of high shopping intensity, such as weekends.
Competition. Online shops reprice against each other, sometimes several times a day, which is why a single day-of-week rule rarely holds.

A rough UK price-drop calendar

The calendar below is a starting point, not a promise. Where a row rests on a source, it is linked.

Product cycles beat the calendar

For technology, the release cycle is the most useful signal. When a manufacturer launches a new generation, the previous one rarely gets worse, but it gets cheaper. If you do not need the latest features, buying the outgoing model a few months after launch is often the best-value move. If you are browsing now, our electronics deals page is a good place to see what is currently discounted across partner retailers.

Seasonal goods

Buying against the season, such as garden furniture in autumn or coats in spring, works because shops want to clear space. The trade-off is choice: sizes and colours run thin. Our guide on buying ahead and paying less covers how to handle that.

Does the day of the week or time of day matter?

Somewhat, but less than the internet suggests. The academic evidence points to markdowns coinciding with busy shopping periods, including weekends. That is a finding about how retailers behave on average, not a rule that Saturday is always cheapest for your product.

Online, many articles claim that prices dip at night or on certain weekdays. Those claims are mostly about flights, which use different pricing systems from high street goods. For general retail, a better habit is to watch the price over several weeks and buy when it reaches the low end of its normal range, whatever day that is.

Flash sales are a separate case: they are short by design, and the pressure to act quickly is part of the pitch. Our flash sale strategies guide explains how to take part without overpaying.

Supermarket yellow stickers: no universal time

Food is where timing matters most to your weekly budget, and where the myths are strongest. Which? looked at yellow-sticker reductions and found no single UK-wide time:

Aldi and M&S: reductions vary by store and are often close to closing time.
Asda: usually reduces twice a day, in the morning and the evening.
Lidl: commonly reduces first thing and again a few hours before closing.
Morrisons, Sainsbury’s, Tesco and Waitrose: told Which? they have no specific standard times, so local store practice decides.

The BBC’s explanation of the system is that it is mainly about inventory management: scanners and staff check how much stock is left, how quickly it is selling and how near it is to its sell-by date. That is why reductions cluster later in the day but are not fixed.

The practical approach is to ask. Staff at your regular store can usually tell you when they do their markdown rounds, and that local knowledge is worth more than any national rule. Remember that the sticker price is not automatically the best value: compare per-unit prices using our unit price checklist.

Black Friday and Boxing Day: the myth and the maths

Black Friday remains the best-known date in the UK price calendar. Which? tracked 175 home, technology and health appliances at eight major UK retailers from May 2024 to May 2025. It found that 83% were cheaper or the same price on at least one occasion outside the four-week Black Friday period.

That does not mean Black Friday is a waste of time. It means it is a good moment to buy only if you know the item’s usual price. Three habits help:

Decide what you want before the event, and note its price in the weeks beforehand.
Set a ceiling price you would be happy with, and walk away above it.
Do not assume the January sales will be better or worse; compare.

We break down the numbers in more detail in Black Friday vs Boxing Day.

How to tell if a price drop is genuine

A falling price only helps if the starting price was honest. Which? experts note that retailers’ “was” prices can mislead, and advise tracking real market prices over six months. Price-history trackers, some built for one retailer and some covering the wider market, show whether the “was” price reflects a genuine saving.

What the rules say

The government’s pricing code of practice gives a benchmark. A reduced-price comparison should generally be based on a product offered at the higher price in the same outlet for at least 28 days in the previous six months. An RRP comparison is allowed when the price was recommended, the trader deals with the supplier on normal commercial terms, and the RRP is not significantly higher than the general selling price at the time.

So a crossed-out figure should have a history behind it. If it does not, treat the discount as marketing.

A five-step check before you buy

Look up the price history for the exact model.
Compare at least two other sellers, using the total at checkout, not the headline price.
Check delivery, returns and any add-ons. A low shelf price can be offset by costs at the end, much as custom mug prices in the UK can hide extras until checkout.
Be wary of countdown timers and “only 2 left” notices that you cannot verify; our fake deals warning lists the common tricks.
Use our guide to comparing prices properly if the products are not identical.

What if the price drops after you buy?

It happens, and the position is less generous than many people hope. Citizens Advice covers the related situation of wrong advertised prices: if you paid more than an item was advertised for, you can return it in its original condition for a refund or ask the shop for the difference. That is about mispriced goods, not ordinary sales.

For a normal price cut after you have bought, there is no general legal right to a partial refund. Some shops run their own price-match or price-adjustment policies, so check the retailer’s terms and contact them quickly. If you are still within the returns window, returning and rebuying at the lower price is another option, though stock may not last.

A related point: in a physical shop, if an item is advertised at the wrong price, you do not have an automatic legal right to buy it at that lower price. The shop can decline to sell at the error price.

Our perspective

We run a platform that sends shoppers to partner retailers, so we see how people actually hunt for deals. Most people ask when to buy; fewer ask whether a discount is real. We think the second question is the more valuable one.

Our view is that timing is a tool, not a trick. Learn the rhythm of what you buy: when new models launch, when the season turns, when your regular supermarket marks down. Then use real-time price checks and filters to compare across retailers rather than relying on one shop’s version of “was”. Waiting only pays when you know the normal price, and rushing only costs you when you do not.

FAQ

When do prices usually drop in the UK?

The main moments are Black Friday in late November and the January sales. Product cycles matter too: older television models, for example, tend to fall in price later in the year and again when new lines arrive. Always compare against the item’s own history rather than the date.

Is Black Friday really the cheapest time to buy?

Not reliably. Which? found that 83% of 175 tracked appliances were cheaper or the same price at least once outside the four-week Black Friday period. It is a good time to buy if the price is at the low end of the item’s normal range.

What is the best time to find yellow-sticker bargains?

There is no single time. Which? found Asda usually reduces in the morning and evening, Lidl early and again a few hours before closing, and Aldi and M&S often near closing, varying by store. Several other chains said they have no standard times, so ask your local store.

What happens if the price drops after I buy something?

There is no general right to a refund of the difference after a normal sale. Check whether the retailer has a price-adjustment policy, and consider returning and rebuying if you are within the returns period. If you were charged more than the advertised price, Citizens Advice says you can return the item for a refund or ask for the difference.

How can I check a discount is genuine?

Look at the price history over about six months and compare the total at checkout across several sellers. Under the pricing code of practice, a reduced price should generally compare to a price the item was offered at for at least 28 days in the previous six months.
