These points could then be converted to vouchers worth £100, which can be spent at one of more than 100 Tesco reward partners.

Customers will continue to be able to earn Clubcard points on their purchases, whether they are participating or not.

Tesco is working with EagleAI for its Clubcard Challenges campaign.

Lizzie Reynolds, Group Membership and Loyalty Director at Tesco said: “We are constantly looking for ways to make Clubcard work harder for our customers.

“With Clubcard Prices on around 8,000 products, it is saving customers up to £360 off the annual cost of their groceries.

“Personalisation is about using what we know about customers to make their experience better and our rewards more helpful and we’re very excited to see how our customers respond to Clubcard Challenges.”

Tesco Clubcard customers can currently earn one point for every £1 spent on qualifying purchases online and in-store.

Points can be exchanged for twice the value in vouchers with Tesco’s more than 100 reward partners.

Reward partners include Cadbury World, Thorpe Park Resort, and Pizza Express.

Customers can also put vouchers towards a three-month Disney+ subscription.

Customers can sign up for a free Tesco Clubcard online.
