This means Tesco shoppers have just this evening and tomorrow to spend the vouchers, worth an estimated £16m.

Tesco vouchers are valid for two years and are sent out in February, May, August and November each year.

The vouchers that are set to expire tomorrow were issued in February 2021, and will become worthless from 1 March.

How does Clubcard work?

Clubcard members collect points every time they spend money in Tesco stores or online.

For every £1 you spend on groceries or £2 you spend on fuel, you get one point. Tesco shoppers can also collect points through Tesco Bank and Tesco Mobile.

You need a minimum of 150 points to get a Clubcard voucher, which is worth £1.50 to spend in Tesco. However, you can triple the value of your points if you exchange them for reward vouchers which can be used with partners such as Thorpe Park, Pizza Express and the RAC.

New Tesco Grocery & Clubcard app

Clubcard members who have ditched their physical Clubcard in favour of scanning their phone at the checkout will need to download a new app from today to avoid missing out on points.

Tesco is axing its Pay+ app today, and shutting its separate Clubcard app on 18 April.

The Tesco Pay+ app lets you store your credit or debit card and Clubcard details. When shopping in a Tesco store, you can then scan a single barcode in the app to pay and collect Clubcard points.

The Clubcard app allows you to scan a digital version of your Clubcard at the checkout in store, as well as view and spend your vouchers.

You can avoid getting caught out at the checkout by downloading and switching to the Tesco Grocery & Clubcard app which is available on Android and iPhone. You won’t lose any points, vouchers or coupons as these will still be available in the new app or via your online account.

This app combines all the features of the two apps that are closing. So as well as using it to pay, you can also view your points balance, spend any Clubcard vouchers, order a grocery delivery and check stock in your local store.
