Halloween is the perfect time to indulge on sweet treats, so Krispy Kreme is getting in the spooky spirit by running a buy one get one free offer today (October 16th).
The American donut brand is giving customers who purchase a Slime Squad donut at Krispy Kreme or Tesco an extra one free of charge - but there's a catch.
Sweet-toothed customers can claim the deal at Tesco supermarkets by showing a special code shared by deal-hunters on hotukdeals.com .
Simply head into a Tesco store and take your Halloween themed donuts to the checkout and show the barcode below to the cashier to redeem the freebie.

Or if you wish to redeem the offer at Krispy Kreme stores, you'll need to show your Rewards card.
Whether you share the extra donut with a friend or save it for yourself, this deal is perfect for celebrating Halloween.
Krispy Kreme's Slime Squad doughnuts were recently launched just in time for the scary season - and they are devilishly delicious.
The limited edition range includes the chocolate orange-filled Jack O Lantern, the Orange Slime Ring and the Toffee Apple Treat.
They won't be available for long, though, so you'll need to get your hands on one before they spookily disappear on October 31.
