Martin Lewis has issued a warning to people who shop at Tesco over an upcoming deadline.
The consumer guru was on ITV's Good Morning Britain, hosting the latest instalment of Wallet Wednesdays. And he reminded Tesco customers that £15m worth of Clubcard vouchers will expire on May 31.
Martin urged people to check online whether they have any of these vouchers and shared a tip for how people can extend their perks. Tesco is reducing its Clubcard Reward perk from 3x to 2x so, for example, you can currently trade in a £5 voucher for three times the value.

This will change to double on June 14 - but Martin urged shoppers to use a trick to extend the life of the voucher, reports the Liverpool Echo. He said: "You go online, spend 50p on a restaurant voucher of your £10. So you now have got £1.50 of your restaurant voucher because 50p becomes £1.50.
"For the rest of the £9.50 they re-issue and it lasts another two years. So if you spend just a little bit of a voucher the rest of it is reissued and it lasts another two years. But otherwise the older vouchers become invalid on May 31."
