Tesco selling giant XL Cadbury Dairy Milk bar cheaper than B&M, Morrisons, Amazon, Sainsbury's, Home Bargains and more

Supermarket shelves are packed with chocolate treats of all shapes and sizes as we head towards Christmas.

And while some undoubtedly make great gifts, they're not always worth the money.

But there's one giant bar of Cadbury Dairy Milk which is being sold at Tesco for less than anywhere else and it weighs a whopping 850g.

The retailer has it on offer, down from the usual £10 to £8 with Tesco Clubcard, which is cheaper than Amazon, Sainsbury's, B&M, Home Bargains, Morrisons and more.

Its weight is the equivalent of around 19 standard 45g bars of Dairy Milk, which cost around 85p each and amount to more than £16.

The good news is that the offer is running right up until Christmas, as it ends on December 23.

And there are loads more Cadbury gifts to choose from this year, including some brand new ones like the 200 Year Selection Box, which has been created to celebrate two centuries of the iconic brand.

It's packed with a variety of the much-loved bars, from vintage classics like the recently re-launched Top Deck, to modern favourites like Cadbury Caramel.

The retail price for the selection box is £8, but again it's on offer at Tesco, where it's £6.50 with a Clubcard between now and December 23.

There are another four new products on the shelves this year too, including Cadbury Mini Puds, a Mini Snowballs Bar, a new Cadbury Dairy Milk Creamy Advent Calendar, and a Toblerone Truffles & Tiny’s Advent Calendar.

And we've already reported how Dairy Milk Chocolate Coins, which disappeared from shelves in 2004, have returned for a second consecutive Christmas.
