CELEBRATIONS have made a huge change to tubs ahead of Christmas – and customers will not be happy.

Chocolate maker Mars has once again slashed the size of its iconic red tub from 550g to 500g – equal to a reduction of around five sweets.

The festive staple is being rolled out of supermarkets ahead of the big day.

Asda is selling the shrunken chocolates for £5.64, with Morrisons and Sainsbury’s charging £7.

The UK’s biggest supermarket is still selling off the larger 550g tubs for £7 or £4.50 on Clubcard price.

It marks the second year in a row the confectionery giant has slimmed down the festive treat.

Last Christmas, the tubs featuring miniature pieces of Twix, Milkyway and Bounty, were reduced in size from 600g to 550g.

The Sun has approached Mars for comment.

At the time, Mars blamed the rising costs of raw materials and operations.

Global cocoa prices are still under pressure due to poor harvests caused by adverse weather in West Africa.

The Energy and Climate Intelligence Unit (ECIU) reported a 43% jump in cocoa prices since 2022.

And Mars is not the only chocolate maker which is slimming down its chocolate tubs.

Quality Street maker Nestle has slashed the size of the purple tubs from 600g to 550g.

The new purple tubs have approximately 57 chocolates – down from 63.

A Nestlé spokesperson cited the cost of manufacturing, “ingredients and transport” for the cut.

Deal expert Tom Church previously told The Sun that the best way to beat size reductions was to look for cut-price deals, such as multi-buy offers in the supermarkets or Nectar and Clubcard prices.

Shrinking chocolate

All major manufacturers are shrinking the size of their treats to help combat rising material costs.

Last month it was discovered that Cadbury cut the size of multipacks of its Brunch bars from five to four.

Instead, a four-bar pack is now on shelves for the same average price of £1.50.

It means the bars – a staple of school lunchboxes – are, in effect, 20 per cent worse value.

Cadbury also reduced packs of Freddos from five to four and Cadbury Dairy Milk multipacks were cut from nine bars to seven.

More recently, the brand slashed the size of it’s Dairy Milk Little Bars multipacks by a third.

How to save money on chocolate

We all love a bit of chocolate from now and then, but you don’t have to break the bank buying your favourite bar.

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.
