Shopper choosing yellow sticker food in a supermarket

Yellow sticker shopping means buying food that a supermarket has marked down because it is nearing its use-by or best-before date. Done well, it cuts a food bill noticeably. Done carelessly, it wastes money on food you cannot use in time. This guide explains how the reductions work, when to find them, how to check that a sticker is a real bargain, and how to handle reduced food safely.

TL;DR

Yellow stickers go on food close to its use-by or best-before date. The deeper cuts usually come later in the day, and timing differs by chain and by store.
A yellow sticker is not automatically the cheapest option. Compare the unit price (per 100g or per 100ml) with the normal price and any multi-buy deal.
Use-by is a safety date, best-before is a quality date. Only buy reduced food you will cook, eat or freeze in time.
Check at the till that the sticker barcode has been scanned, so the reduction is applied.
Plan meals around what you find, not the other way round, and keep a stocked freezer.

What yellow sticker shopping actually is

The yellow sticker is the label supermarkets put on products that are approaching their use-by or best-before date. Researchers at Leeds Beckett University describe yellow-sticker shopping as actively targeting these reduced goods. The sticker often overrides the original barcode, and the discount encourages the food to leave the shelf before it expires, which also helps reduce food waste.

The same study makes a point that experienced shoppers will recognise: this is a skill, not just a discount hunt. It draws on knowing how to move around a store, how to store food and how to cook. That is why two people can walk past the same chiller cabinet and only one of them comes away with a good dinner for a fraction of the usual price.

How stores decide what to reduce

Reductions are not random. According to the BBC, supermarket scanner systems look at how much stock is left and how quickly it is selling, then suggest price cuts. That helps explain why more yellow-sticker goods appear in the evening, when a store can see that certain items are not going to sell at full price.

For you, the practical lesson is that stock levels matter. A busy Friday afternoon may leave little behind, while a quiet midweek evening may leave plenty.

When to find yellow stickers in UK supermarkets

There is no single national timetable. Each chain has its own routine, and individual stores adjust it. Which? has reported the typical patterns:

Retailer type	Typical pattern
Asda	Usually reduces twice a day, in the morning and in the evening
Lidl	Tends to reduce first thing and a few hours before closing, but can reduce throughout the day
Aldi	Varies by store, but reductions are likely near closing
M&S	Varies by store, but reductions are likely near closing

These are the patterns in Which?'s guide to the best times of day. Treat them as a starting point. The most reliable method is to visit your own local stores at different times for a couple of weeks and note when the stickers appear.

The red sticker exception

Not every discount is yellow. The Sun reports that Aldi typically marks down perishable products by up to 75% on their last day of shelf life, near closing time, and uses red stickers rather than yellow. If you shop there, look for the colour as well as the discount.

Big stores, small stores, and the day of the week

A large out-of-town supermarket generally has more stock to clear than a small convenience store, so there is more choice. Smaller stores restock more often and may have fewer reductions, but the ones they have can go quickly. Whichever you use, ask a member of staff when the reduction round usually happens. Many are happy to tell you, and it saves repeated wasted trips.

How much can you really save?

This is the question most people ask first, and the honest answer is: it depends on your household, your store and how flexible you are. Reported figures vary widely. Newspaper profiles feature shoppers who say they halve their grocery spending, and some websites quote weekly savings in the tens of pounds. These are individual claims, not guaranteed results, and they tend to come from people who shop several times a week, cook from scratch and freeze heavily.

A more cautious way to think about it is to measure your own saving:

Note the full price of an item before reduction.
Note what you paid.
Add up the difference across a month, then subtract anything you threw away.

That last step is the important one. A 75% reduction on food you bin is a 100% loss. A modest 25% cut on something you were going to buy anyway is a real saving.

The discount size also changes with timing. Early reductions are often small, and later ones deeper. Shoppers have complained about this, with a 2026 news report describing frustration at small reductions on fresh food at the large chains. If a sticker only takes a few pence off, it may be worth waiting, buying something else, or choosing a different store.

Is the yellow sticker really the cheapest price?

Not always. A yellow sticker feels like a bargain, but it should be tested against the alternatives, just like any other offer. A Morrisons shopper pointed out, in a case reported in the press in 2022, that some items can cost more with a yellow sticker than on a multi-buy deal. A single reduced pack can look cheap while a multi-buy on fresh packs works out cheaper per portion.

The fix is simple and does not need a calculator for most items:

Compare unit prices. Which? recommends using the price per 100g or 100ml rather than the overall pack price to work out price differences between items.
Compare the sticker with the multi-buy. If the multi-buy price per portion is lower, the sticker is not the deal.
Compare pack sizes. A larger reduced pack is only good value if you will use all of it.
Compare with the budget range. A reduced premium product can still cost more than the standard own-brand version of the same thing.

If you want a method for this, our guides on how to compare prices properly and a one-minute unit price checklist walk through the checks step by step. The same habit helps whether you are comparing a reduced chicken breast or a kitchen appliance.

Pricing integrity matters here too. The Competition and Markets Authority has noted that consumer confidence in pricing and promotional activity is a key driver of competition. In practice, that means checking what you are being offered rather than trusting the colour of a label.

Use-by, best-before and what they mean for reduced food

This is where yellow-sticker shopping needs care. The two date types are very different, and reduced food will often be close to either.

Use-by is about safety. GOV.UK says you can eat the food until and on the date, but not after it.
Best-before is about quality. The food may be safe to eat after the date, but may not be at its best.

The guidance also warns against relying on the sniff test for anything with a use-by date. Harmful bacteria that cause food poisoning cannot be detected by smell or taste, so food past its use-by date should not be eaten even if it looks and smells fine.

What this means at the shelf:

For raw meat, fish, ready meals and cooked meats with a use-by date of today, decide before you buy: will you cook it tonight, or freeze it today?
For bread, biscuits, cereals, tins and other best-before items, a reduction is low risk, because quality rather than safety is the issue.
If you have a health condition, are pregnant, or are feeding someone very young or elderly, take extra care with chilled and cooked foods. Ask your GP, pharmacist or midwife about which foods to avoid.

Freezing yellow-sticker food safely

Freezing is the main tool that makes a late reduction useful. A Food Standards Agency review explains that freezing pauses the growth of bacteria and their toxin production. In practice, that means you can freeze food bought on its use-by date, provided you do it before the date passes and treat it properly afterwards.

A few habits make this work:

Freeze on the day you buy. Do not leave the food in the fridge and hope. Get it into the freezer as soon as you are home.
Portion before freezing. Split mince, chicken and sausages into meal-size bags, so you defrost only what you need.
Label with the date. A marker and a freezer bag take ten seconds and save guessing later.
Defrost in the fridge, not on the worktop, and cook it once defrosted.
Do not refreeze raw food that you have defrosted without cooking it first.

BBC Food’s advice is blunt and sensible: only buy reduced food if you are certain you will use it within a day or two, or if you are prepared to process and freeze it immediately.

A practical routine for yellow sticker trips

The best yellow-sticker shoppers are not luckier, they are better prepared. This routine is simple enough to follow on a normal week.

Before you go

Learn your local stores’ reduction routines, as described above. Check your freezer space and your cupboard staples. Keep versatile basics, such as rice, pasta, tinned tomatoes, onions, stock cubes and frozen vegetables, so almost any reduced protein becomes a meal. BBC Food suggests keeping a freezer stocked with versatile basics to pair with discounted items.

Pantry staples and frozen vegetables for meals

A shopping list is still useful, but make it flexible. Write categories (“a protein”, “two vegetables”, “something for lunches”) rather than fixed products.

In the store

Walk the reduced section first, not last. Look at the chilled meat, fish, bakery, dairy, ready meals and fruit and veg. Check the date on every item, pick up what fits your plan, and use the unit price to compare similar products.

Reduced items are not always in one place. Some stores keep a dedicated chiller, others put stickers on products in their normal spot, so a quick walk around the fresh aisles can turn up more.

At the till

Make sure the yellow-sticker barcode is scanned, not the original product barcode, so the reduction is applied. The Sun’s advice on supermarket yellow stickers is to check this, and it is worth glancing at the receipt before you leave. At self-checkout, scan the sticker barcode carefully and watch the screen.

At home

Put the use-by items to use first, freeze what you cannot cook within a day or two, and write down what is in the freezer. Then plan the week’s meals around what you have found. BBC Food describes this as flipping the usual process: start with the ingredients available and work out the meal, which makes yellow-sticker shopping more intuitive and effective. If you want a structure for this, our guide to meal planning on a budget shows a weekly method that fits well with reduced food.

Yellow stickers versus other ways to cut the food bill

Yellow stickers are one tool. They work best when you combine them with others.

Method	Best for	Watch out for
Yellow stickers	Meat, fish, bakery, ready meals you can freeze	Unpredictable stock, small discounts, food you do not use
Multi-buy deals	Items with long dates that you buy regularly	Paying more per unit than a single reduced pack
Own-brand and budget ranges	Staples you buy every week	Assuming own-brand is always cheapest per 100g
Switching supermarket	Big weekly shops	Travel cost and time

Our view: apply the yellow-sticker mindset beyond food

At ZoneOffer we spend our time looking at discounts, and the habits that make yellow-sticker shopping work are the same habits that make any bargain hunting work. We think there are three:

Start with the real price. A reduction is only a saving if the end price is lower than your realistic alternative. That is why we favour unit prices and checkout totals over headline percentages.
Buy what you would have bought anyway. A good deal on something you do not need is still money spent.
Timing and patience beat speed. Whether it is a late-evening chiller or an out-of-season purchase, waiting for the right moment is often the best discount you can get. Our guide to out of season shopping applies the same thinking to non-food items.

We do not claim yellow stickers will transform every budget. They suit people with some flexibility, a freezer and a willingness to cook. For everyone else, careful comparison on regular purchases is just as valuable.

Common mistakes to avoid

Buying too much. The fridge and freezer are finite, and a full trolley of reduced food can leave you throwing some away.
Ignoring the date. A use-by date of today is only a bargain if you act today.
Trusting the label over the numbers. Compare unit prices and multi-buys, as above.
Not checking the receipt. If the sticker did not scan, ask for the reduction at customer service.
Eating for the sticker, not the plan. Rotate your meals so that reduced food does not become a week of the same thing.

FAQ

What time do supermarkets put yellow stickers on?

There is no fixed time across the UK, because it differs by chain and by store. Which? reports that Asda usually reduces twice a day, morning and evening, while Lidl tends to reduce first thing and a few hours before closing. Aldi and M&S vary by store but are likely to reduce near closing, so ask staff at your local branch.

Can you freeze food bought with a yellow sticker?

Often yes, if you freeze it before the use-by date passes. The Food Standards Agency’s review says freezing pauses the growth of bacteria and toxin production. Freeze it on the day you buy it, defrost it in the fridge and cook it once defrosted.

Is it safe to eat food after its date?

It depends on the date type. Use-by is a safety date and the food must not be eaten after it, even if it smells fine. Best-before is about quality, so food may still be safe after the date but may not be at its best.

Is a yellow sticker always the cheapest price?

No. A multi-buy deal or a cheaper own-brand version can work out lower per 100g or per portion. Compare unit prices before you decide, and make sure you will use the whole pack.
