Tesco is urging Clubcard members to check if they have any Clubcard Vouchers that need to be used up, as £16.5 million-worth are set to expire at the end of this month.

The vouchers, which are valid for two years, must be exchanged before midnight on November 30.

Shama Wilson, group membership and loyalty director at Tesco, said: “We don’t want anyone to miss out on making the most of their Tesco Clubcard Vouchers, and with some great new offers with Clubcard Rewards, this really is a great time to use those vouchers up.”

The expiring Clubcard vouchers can be put towards the cost of their weekly supermarket shop, fuel or a new deal with Tesco Mobile.

The supermarket giant said customers can also exchange them for double their value with more than 100 Clubcard reward partners.

These include the new Tesco Tuesdays offer with Cineworld, where Clubcard members can get cinema tickets for Tuesday showings for just £5 (£2.50 in Clubcard Vouchers).

There is also a new triple-value voucher offer up for grabs with PizzaExpress, meaning £10 of Tesco Clubcard vouchers can be redeemed for a code worth £30 off food at the iconic pizzeria.

Ms Wilson added: “The value of vouchers expiring is higher than usual this quarter.”

“If all the vouchers expiring were used for Tesco Tuesdays, it would be enough to get 6.6million cinema tickets at Cineworld. If they were exchanged with PizzaExpress, they could secure an amazing £49.5million of reward codes towards food, so it really is worth checking in the Tesco app to see if you have any vouchers expiring.”

Tesco Clubcard members can earn Clubcard points in various ways, including using their Clubcard when shopping or purchasing fuel at Tesco, or when charging electric vehicles at Pod charging facilities located in Tesco stores.

Today, more than 24 million UK households have a Tesco Clubcard, and members can keep tabs on all the latest Clubcard Reward Partner deals with the Tesco app.
