TESCO has issued an urgent warning to its shoppers ahead of the summer months.
The supermarket’s Clubcard scheme saves Brits thousands of pounds but they could lose money if they don’t act fast.
Tesco has urged shoppers to use their Clubcard points ahead of May 31.
At the end of the month, the supermarket will be wiping millions of pounds worth of unused vouchers from shoppers’ cards.
The chain emailed certain customers ahead of the huge change.
The email read: "Your Clubcard vouchers are expiring soon.

"Don't forget to use them on your next shop."
Clubcard vouchers are valid for two years from the date of issue.
That means any vouchers issued in mid-2023 are set to expire.
Vouchers can be found on the Tesco Clubcard website or on the Tesco app.

They are earned through spending at the supermarket and scanning your card at the checkouts.
The supermarket occasionally offers shoppers ways of earning points faster.
On May 5, the supermarket launched its Tesco Clubcard Challenges which offers free points to shoppers when they reach certain targets.
The offer is tailored to individual shopping habits, meaning that everyone’s challenges are different.
Other companies including OVO Energy, Vauxhall and Esso all offer exclusive Clubcard deals too.
Occasionally, Tesco partners with TV shows to launch incredible promotions which can help you rack up points fast.
Viewers who cast five votes during an episode of Britain’s Got Talent are eligible for a staggering 50 Clubcard points a week.
