In larger stores only

If you're visiting a larger Sainsbury's store (find your nearest), you may be able to pick up a 'Taste Me, Don’t Waste Me’ box of surplus fruit and veg for £2, while stock lasts. The boxes contain fresh fruit and vegetables that would have otherwise gone to waste.

Sainsbury's says the boxes are a permanent feature, though they will be subject to availability. Look out for them in larger stores, rather than Locals (and you can't get them online).

If boxes are available, they'll be in the fresh produce aisle. What you'll get is completely random, though Sainsbury's says typical contents could include: apples, bananas, broccoli, carrots, cauliflower, courgettes, oranges, peppers, plums, red cabbage, and swede.

To give you a rough idea of how much of a saving you could make, we've made some calculations based on the products mentioned above:

One pack apples (six in pack) – normally 99p (17p each)
One pack Fairtrade bananas (five in a pack) – normally 78p (16p each)
One loose broccoli – around 72p (depending on weight)
One loose cauliflower – normally £1.19
One pack courgettes (500g) – normally £1.45
Loose orange – normally 30p
Loose red pepper – normally 69p
One punnet of plums (400g) – normally £1.29
Loose red cabbage – normally 75p
Loose swede – normally 62p

Based on the price of each individual item in the box, we've calculated it would cost about £9 to buy it all separately – so we reckon buying a box for £2 is a good deal.

MSE Georgia-May says:

I managed to get my hands on a Sainsbury's veg box back in 2023 and it had:

One pack of spinach (260g) – normally £1.50
Five loose easy peelers – normally 30p each
Two loose peppers – normally 50p each
Two loose bananas – around 17p each (depending on weight)
One loose avocado – normally 75p each
One loose broccoli – around 72p (depending on weight)
Three loose plums – around 50p
Nine loose potatoes – around £1.08

Based on what these items would roughly cost to buy individually in 2025, the total value would come to £7.40. The side of the box advised it had a shelf life of six days, so I think this is great value.

Since I picked this box up in 2023, we've seen many similar boxes:

Across all departments

Sainsbury’s launched its online and in-store Black Friday sale on Tu clothing on Friday 21 November and is offering a blanket discount of 20% off everything until Saturday 29 November. There is no code needed as the discount is automatically applied.

The sale is also extended to branded items from Fatface, French Connection and Wallis, so if you find these brands don't have a good discount on for Black Friday this year you could shop them via Sainsbury's instead.

The discount is lower this year, as Sainsbury’s previously offered 25% off items in 2024 and 2023.

Delivery costs £3.95, and collection in-store (find your nearest) is available when you spend over £10.

Some examples we spotted on Friday 21 November:

Disney Lilo & Stitch Knitted Set – £12 (was £15)
Elevated Fossil Tapered Co-ord Joggers – £16 (was £20)
FATFACE Ashby Pull On Denim Shorts – £19.60 (was £24.50)
Light Blue Lambs Wool Half Zip Jumper – £28 (was £35)

Important: Don’t allow yourself to be taken in by the hype around Black Friday and be sucked into buying something you don’t need or can’t afford. Always do your own price comparisons to ensure you are getting the best deal possible – don’t just take a retailer’s word for it.

Free protection for all shopping!

There's a little-known piece of legislation that turns any credit card into a financial self-defence superhero. 'Section 75' of the Consumer Credit Act means your plastic must protect anything you buy for more than £100 for free, so if there's a problem or the company goes bust, you can still get your money back.
And although Section 75 doesn't apply to debit cards, there is something else to fall back on if you've paid using a debit card, or used a credit card for a purchase under £100. Known as Chargeback, this is part of banks' and card companies' internal rules and not a legal requirement. Read full details of Section 75 or Chargeback, plus how to claim, in our guides.
What the * means above
If a link has an * by it, that means it is an affiliated link and therefore it helps MoneySavingExpert stay free to use, as it is tracked to us. If you go through it, it can sometimes result in a payment or benefit to the site. It's worth noting this means the third party used may be named on any credit agreements.
You shouldn’t notice any difference and the link will never negatively impact the product. Plus the editorial line (the things we write) is NEVER impacted by these links. We aim to look at all available products. If it isn't possible to get an affiliate link for the top deal, it is still included in exactly the same way, just with a non-paying link.
