Three million Tesco Clubcard holders could get up to £50 in extra Clubcard points from next week.
The points can be spent at Tesco, or exchanged with Tesco’s reward partners for twice the value – meaning customers could get a voucher of up to £100.
The new Clubcard Challenges initiative will launch on Monday and last for six weeks.
If members take part, they will be sent 20 challenges, which have been personalised just for them.
For example, it might be their challenge is to “spend £20 on Summer BBQ range over the next six weeks” or “spend £10 on plant-based meals”.
If they complete the challenge, they’ll be rewarded with extra Clubcard points.
There will be 20 offers available, customers can choose which 10 they would like to complete.
Whether they take part or not, Clubcard members will still be able to earn Clubcard points on purchases and access Clubcard Prices.
Tesco will use AI technology to give customers a personalised challenge, with the help of EagleAI.
The supermarket said it is looking for more ways to make the Clubcard rewards “personal and relevant” for members.
Tesco issued 289 million personalised coupons to customers over the last year, and said it saw a “significant” increase in the number being redeemed.
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.”
There are also millions of pounds worth of Clubcard Reward Partner codes that are expiring soon.
More than £27million of expiring codes will need to be used over the next few weeks, including more than £16million worth of rewards for days out and eating out.
The supermarket said it had emailed customers with reminders and is encouraging people to check to see if their vouchers or reward codes are set to expire via the Tesco Grocery and Clubcard app.
Ashwin Prasad, Tesco Chief Commercial Officer, said: “With millions of vouchers expiring at the end of this month, we are urging everyone to make the most of their Clubcard this May and check to see if any vouchers or reward codes are expiring.”
