It might be a good idea to do your next weekly shop at Tesco because £16.5 million worth of Clubcard vouchers are about to expire at the end of November. The vouchers, which are valid for two years, need to be exchanged before the clock strikes midnight on the evening of November 30.

You can use these vouchers for several things. It could be for your weekly shop, to pay for fuel or for your mobile plan on Tesco Mobile. Customers can also exchange them for double their value with more than 100 Clubcard reward partners, or can even take advantage of some great new Reward Partner deals.

These include the new Tesco Tuesdays offer with Cineworld, allowing Clubcard members to get cinema tickets for Tuesday showings for just £5 (£2.50 in Clubcard Vouchers). There is also the new triple value voucher offer with PizzaExpress, meaning £10 of Tesco Clubcard vouchers can be redeemed for a code for £30 off food at the iconic pizzeria.

Tesco Group Membership and Loyalty Director Shama Wilson 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 value of vouchers expiring is higher than usual this quarter, and 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."

To earn Clubcard points you have to scan your Clubcard when you pay for your shop or for your fuel at Tesco. You can also get them when charging electric vehicles at Pod charging facilities at Tesco stores. More than 24 million UK households have a Tesco Clubcard today.
