TESCO shoppers have just hours left to use Clubcard vouchers worth £18million or risk losing them forever. Customers have until just 11.59pm today to claim their rewards points before they expire.

To see outstanding vouchers and the date when they expire, log in to your Tesco.com account, go to the 'Clubcard account', and select 'vouchers'. For those using the Tesco mobile app, click onto your 'clubcard' section and then 'vouchers'.

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 Clubcard shoppers have been issued with a warning over their vouchers. If the points aren't used before the deadline of midnight tonight, then they will expire
