Tesco Clubcard vouchers can be redeemed every three months, in February, May, August, and November. Card holders can manage and track their vouchers using the Clubcard app or via the Tesco website. With many people's vouchers set to expire at the end of August, Martin Lewis ' Money Saving Expert team have shared a tip that could help you keep a hold on your points, as reported by the Mirror. If you make even a small purchase on the Tesco Clubcard Rewards website, you'll get the remaining points credited back to your account.
