Tesco shoppers have less than one month to spend more than £16million worth of Clubcard vouchers before they expire.

The supermarket issues Clubcard vouchers every three months - in February, May, August and November - and they last for two years. The ones expiring soon will run out on November 30, having first been sent to customers in November 2021.

Tesco shoppers get one Clubcard point for every £1 spent on groceries in stores and online, or if you have a car, drivers can get one point for every two litres of fuel you buy at Tesco petrol stations. Additionally, every £1 spent on Tesco Mobile is worth one point, while every £4 spent on a Tesco credit card is also worth one point. You'll also get one point for every £1 spent using a Tesco Clubcard Pay+ debit card.

You need a minimum of 150 points to get a Clubcard voucher, which will be worth £1.50 to spend in Tesco. It is possible to double the value of your points if you use them with a “Rewards Partner” - you can spend your vouchers include Thorpe Park, Pizza Express and the RAC.

Emma Botton, Tesco Group Customer Director, said: “We want to help customers’ household budgets stretch further right now and Clubcard is the best way to get great value with Tesco. With more than £16million worth of Clubcard vouchers due to expire at the end of November, we’re reminding customers to spend them now – or even use them to get ahead with some early Christmas shopping.”

If you’re not ready to spend your vouchers, there is a way to extend them and make them last longer. Go to the Tesco Clubcard Rewards website and make a small purchase for 50p worth of Clubcard points - the remainder of your Clubcard voucher balance will then be credited back to you as points.

These points will be turned into vouchers again when Tesco next issues you a Clubcard statement. You will need to do this for every voucher you have though - so it may not be worth it for smaller amounts.

You can check your Clubcard balance by logging into the Tesco Clubcard website with your account details. Once you are logged in, click on “my Clubcard account” and then “vouchers” and you should see a table listing the vouchers you still have to spend. Tesco has around 20 million Clubcard members.
