Earlier this month, Tesco shoppers were issued with a two-week warning to spend their Clubcard vouchers before they expire at the end of May.
Customers who received their coupons in May 2020 have had two years to spend their reward amount. Now, they must be cashed in by the end of this month, else they will become unusable.
There are still around £17million of Clubcard vouchers that have not been spent. Shoppers can check if they have forgotten vouchers by logging into the Tesco Clubcard website.
