Martin Lewis has issued a countdown warning to everyone with a Tesco Clubcard where if you don't act quick, you'll lose out. The Money Saving Expert (MSE) founder sent out the alert in his latest MSE newsletter, which hits the inboxes of thousands of people signed up to the latest hacks and warnings offered by the Mancunian finance journalist.

Money expert Martin Lewis has issued a warning to everyone with a Tesco Clubcard. This weekend, 18 million Tesco Clubcard money off vouchers are expiring, which means you’ll no longer be able to use them for money off your shopping this Christmas, or be able to convert them to other rewards via Tesco’s app.

If you are one of the 16.3 million people who hold a Tesco Clubcard, you need to pay attention to this warning from Martin Lewis's Money Saving Expert brand.

Tesco - which is rivalled by the likes of Lidl, Aldi, Morrisons, Asda and Sainsbury's - has issued a warning to its 20million Clubcard holders earlier this month.
