Major supermarket slashes price of HUGE Quality Street bags from £10 to £5 – they’re cheaper than tubs

These points can then be turned into vouchers for money off food at the supermarket, or discounts at other places like restaurants and days out.

Each time you spend £1 in-store and online, you get one point when you scan your Clubcard.

Drivers using the loyalty card get one point for every two litres spent on fuel.

One point equals 1p, so 150 points gets you a £1.50 money-off voucher, for example.

You can double their worth when you swap them for discounts with "reward partners".

For example, £12 worth of vouchers can be swapped for a £24 three-month subscription to Disney+.

Or you can swap 50p worth of points for £1 to spend at Hungry Horse pubs.

Where you can spend them changes regularly, and you can check on the Tesco website what's available now.

Tesco shoppers can also get Clubcard prices when they have the loyalty card.

The discounted items change regularly and without a Clubcard you'll pay a higher price.

These Clubcard prices are usually labelled on shelves, along with the non-member price.

But it's worth noting that just because it's discounted doesn't necessarily make it the cheapest around, and you should compare prices to find the best deal.

You can sign up to get a Tesco Clubcard in store or online via the Tesco website.

Here we round up what saving programmes you'll find at the big brands.

• Iceland: Unlike other stores, you don't collect points with the Iceland Bonus Card. Instead, you load it up with money and Iceland will give you £1 for every £20 you save.
• Lidl Plus: Lidl customers don't collect points when they shop, and are instead rewarded with personalised vouchers that gives them money off at the till.
• Morrisons: The My Morrisons: Make Good Things Happen replaces the More Card and rewards customers with personalised money off vouchers via the app.
• Sainsbury's: While Sainsbury's doesn't have a personal scheme, it does own the Nectar card which can also be used in Argos, eBay and other shops. You need 200 Nectar points to save up £1 to spend on your card. You need to spend at least £1 to get one Nectar point.
• Tesco: Tesco Clubcard has over 17million members in the UK alone. You use it each time you shop and build up points that can be turned into vouchers - 150 points gets you a £1.50 voucher. Here you need to spend £1 in Tesco to get one point.
• Waitrose: myWaitrose also doesn't allow you to collect points but instead you'll get access to free hot drinks, and discounts off certain brands in store.

Consumer reporter Sam Walker reveals how to cut costs...

Go own brand - if you're not too fussed about flavour and just want to supplant your chocolate cravings, you'll save by going for the supermarket's own brand bars.

Shop around - if you've spotted your favourite variety at the supermarket, make sure you check if it's cheaper elsewhere.

Websites like Trolley.co.uk let you compare prices on products across all the major chains to see if you're getting the best deal.

Look out for yellow stickers - supermarket staff put yellow, and sometimes orange and red, stickers on to products to show they've been reduced.

They usually do this if the product is coming to the end of its best-before date or the packaging is slightly damaged.

Buy bigger bars - most of the time, but not always, chocolate is cheaper per 100g the larger the bar.

So if you've got the appetite, and you were going to buy a hefty amount of chocolate anyway, you might as well go bigger.
