Via cashback. Get item from Tesco, Sainsbury's or Ocado only

If you buy a pack of Onken Kiddos kids' yogurts 4x90g at Tesco, Sainsbury's or Ocado, you can get up to £2.40 back – paid into a PayPal or bank account – via marketing platform Hashting.

When we checked, the yogurts were £1.50 to £2.25 at the supermarkets, so the cashback makes the item free. You'll only get back what you paid, up to £2.40.

To claim, go online to Hashting (it's best viewed on a mobile), and confusingly you'll be sent another link to claim via WhatsApp, or if you'd prefer, sent via text message – so you'll have to give your mobile number if you don't use WhatsApp. After you've bought the product, you'll need to take a photo of your receipt and upload it as proof of purchase.

This offer will end at 11.59pm on Sunday 31 May or when 3,000 redemptions have been made. Each household can apply for cashback once.

Eligible varieties:

• Raspberry & banana

• Blueberry, blackberry & banana

Hashting says you should receive your cashback within 30 days – see full terms and conditions.

For new customers only

If you’re new to Morrisons Now* (the supermarket’s speedy delivery service), you can get £10 off when spending £50 or more by Monday 20 April.

To get the deal, switch to 'Morrisons Now' in your online grocery account, add a maximum of 35 items to your basket (the most it allows), then enter the code fast10 at checkout.

It's available from 350+ Morrisons stores (see the full list or use its postcode checker), and it says you'll typically have your groceries delivered within one hour. Delivery's £2.99.

When we checked prices, we noticed Morrisons Now generally didn’t price match other supermarkets like Morrisons, so watch out for these fluctuations. Generally, though, prices on both online sites were broadly the same.

Only one code can be used per household, and it can't be redeemed against certain items – see 'More info' below.

For new online customers only

Orders must be delivered by Friday 1 May. Despite the name of the code, you don’t have to have a PayPal account to use it – you can use other payment methods at checkout.

Plus, until Thursday 16 April, Iceland is offering free same-day delivery if you’re spending over £40. It says its slots run until 9pm each day. Outside of this promotion, Iceland offers free next-day delivery on orders over £40. No extra code is needed, you'll automatically get free delivery with this offer.

Asda says a unique code will be emailed to you within two hours. Apply this code at checkout and make sure your order is collected or delivered by 11.59pm on Thursday 14 May. Note though, this deal is limited to the first 15,000 customers who use their code, so the deal could end sooner.

Some excluded items don't count towards the £60 minimum spend – see 'More info' below.

Via Blue Light Card, valid till 24 April

If you've a Blue Light Card (£4.99 for two years – see more info), you'll be able to get a code for 10% off at Morrisons if you spend over £40 in-store on Fridays until 24 April. You can get your code via the Blue Light Card app from 7am each Friday.

The discount can be used once per Friday. You can only use the discount in Morrisons main supermarkets, not at Morrisons Daily or petrol station locations. Blue Light Card says the maximum discount you can receive is £70 per transaction – and of course, it's unlikely most will be doing a £700+ grocery shop. See 'More info' for excluded purchase items.

We've seen reports online of people having connection issues in stores, so it's a good idea to download your barcode before you go to shop.

Fancy a brew after your shop? Blue Light Card holders can get 10% off in Morrisons Cafés.

Every day with its loyalty card when you bring your own cup

If you sign up for a myWaitrose loyalty card - you can get a free regular-sized tea or coffee in-store every day from the self-serve machine, when you use your own reusable cup in selected stores. You can choose from americano, cappuccino, latte or tea.

If you haven't got one already, you'll receive your physical myWaitrose loyalty card within five weeks of signing up via the link above. Alternatively, you can download a myWaitrose card via the app (free in the App Store or Google Play).

Simply swipe your card at the till – you can then go and get your free drink using your reusable cup. You need to scan your loyalty card in order to use the machine and redeem your drink.

Why do I have to provide my own cup? Waitrose used to hand out disposable coffee cups for this freebie, but in 2018 it stopped this for environmental reasons. For where else you can save with a reusable cup, see our own-cup discounts blog.

Includes a main, side, starter or dessert

If you fancy a pizza, but want to save your dough, this M&S meal deal could be one for you.

Go into an M&S (find your nearest*) and you can pick up its £14 Pizza Night dine-in meal deal which includes two pizzas and two sides. M&S says this'll feed four. This is an on-going offer with no end date. A pizza would usually cost £6 by itself, so with another and two sides, we think this is good value.

What's on the menu? 

The M&S website* lists 12 pizzas and 12 sides to to mix and match as you wish (subject to availability). A few highlights we spotted on the menu include:

Pizzas 🍕

• Margherita

• Smoked ham and cheese

• Spicy beef

Sides 🥦

• Mac and cheese bites

• Dirty fries

• Mozzarella sticks

For Iceland Bonus card holders. In stores only

If you're aged 60 or over, you can get 10% off your shopping at all Iceland (find your nearest*) or The Food Warehouse (find your nearest) stores nationwide, every Tuesday when you show valid ID and an Iceland Bonus card (its loyalty scheme – sign up for free* if you don't have one).

To receive the over-60s discount, simply show proof of age at the checkout – either a driving licence, senior bus pass, senior railcard, or freedom pass (although freedom passes can only be used as ID in London stores). If you’re in Scotland or Wales, you can’t get the discount on alcohol. See full T&Cs*.

When you spend up to £250 in a calendar month

New and existing users of the Lidl Plus app (download via App Store or Google Play) in England, Wales and Scotland will receive a 10% off voucher when spending £250 in a calendar month – up to a maximum of £20. If you spend £100 in a month, Lidl told us you will qualify for a free own-brand item, and then again if you spend £150.

Lidl Plus is also available in Northern Ireland, but tends to have different offers.

As well as money-off coupons, you can claim a free in-store bakery item when you've spent at least £10 in a month. To track the amount spent, scan your virtual Lidl Plus card (within the app) each time you shop. Of course, this shouldn't be an excuse to overspend, but it could be a nice bonus when doing your normal shopping anyway.

Once you've reached the spend target, your coupons should appear automatically in the Coupons section of the app. You can't get change from the coupons, and you'll need to use them within seven days of issue at any Lidl store in the UK (find your nearest).

The qualifying spend excludes infant formula, and coupons can't be used on alcohol or infant formula.

What else you can get from the app – 20% off in-store bakery items and weekly coupons

Check the 'Coupons' section of the Lidl Plus app weekly for extra offers. You can get 20% off all in-store bakery items on Monday to Saturday (excluding bank holidays) from 7pm until closing time.

Every Thursday, you'll be offered a different selection of item-specific coupons valid for one week. When we checked, you could get 20% off cookies and 15% off salted nuts, bacon and stonebaked pizzas.

The Lidl Plus app for Northern Ireland customers

To use the app, select Northern Ireland when signing up. Each week, the app will have 10 coupons for selected products, usually up to 33% off. MoneySaver Glenda K told us she's previously seen 33% off organic honey, 30% off smoked bacon and 25% off ground coffee.

How to use the Lidl Plus app

Scan your virtual card at the till or self-service till each time you shop. Spend coupons by loading them onto your virtual card, then scanning your card before paying. You can use more than one coupon at the same time, but Lidl says there may be a limit of six promotional items per customer.

For more ways to save on the weekly shop, whichever supermarket you frequent, see our supermarket coupons.

Slightly past its best, but still edible. In stores nationwide, excluding Northern Ireland

If you head into a Lidl store (find your nearest), you can pick up a 5kg 'Waste Not' box of fruit and vegetables for £2, while stock lasts. The boxes contain 'edible but not perfect' fruit and veg, which are slightly past its best, but still safe to eat. This is currently an ongoing offer with no end date, but we'll update here if that changes.

These are available in stores in England, Scotland, and Wales, and found near the checkout area. They're subject to availability, so if you want one you'll need to be quick as there are only a limited number of boxes available each day. Lidl says any unsold boxes will be donated to local good causes.

What you'll actually get is completely random, as the boxes are made up on the day with whatever fruit and veg is looking past its best in each store. Some could be damaged or discoloured, but you'll be able to see what you're getting before you buy.

^{A box we spotted in Aug 2023 in a London branch of Lidl}

To give you a rough idea of how much of a saving you could make, when we picked up a box to check this deal out, we got:

• One 250g punnet of raspberries – normally £2.99

• Two bananas – normally 37p for two (£0.78/kg)

• Five apples – normally 89p for a five-pack (17p each)

• 13 satsumas – normally 95p for a 500g bag (£1.90/kg)

• Two pears – normally 95p for a 550g bag (£1.72/kg)

• One 500g pack of leeks – normally 69p for a 500g pack (£1.38/kg)

• Two aubergines – normally 69p each

• Three lettuce – normally 69p for a two-pack (34p for one)

• 13 potatoes – normally 91p for a 2.5kg bag (36p/kg)

• One punnet of black grapes – normally £1.09

Based on the price of each individual item in the box, we've calculated that it would cost over £10 to buy it all separately – so buying a box for £2 really does save a bunch.

Don't have a Lidl near you? Try Sainsbury's similar fruit & veg box.

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.

Often includes potatoes, carrots, peas & more

If you go in-store or online at Morrisons, you can get selected vegetables and fruit branded 'wonky', which may be slightly irregular in shape or appearance, but totally fine to eat.

In most cases, it's the cheapest way to eat fresh at Morrisons, and means it's often priced competitively against other major supermarkets. What's available will depend on the season and stock in your local store.

Be aware that wonky doesn't always mean cheaper. When we checked, you could get a bag of 15 apples for £2.50, but only four 'wonky' apples for £1.19.

Often includes potatoes, carrots, apples & more

If you go in-store or online at Waitrose, you can get selected vegetables and fruit branded 'wonky', which may be slightly irregular in shape or appearance, but totally fine to eat.

What's available will depend on the season and stock in your local store. Here's what we found at one Waitrose store:

Although Waitrose is rarely the most MoneySaving supermarket, if you're shopping there anyway, its wonky fruit and vegetables are a great option for healthy eating.
