Tesco Clubcard members are being urged to check what they are sitting on, as Tesco today reveals more than half a million shoppers have more than £100 in unused Clubcard vouchers. In addition to more than 500,000 shoppers with more than £100 of Clubcard vouchers in their accounts, there are more than 95,000 shoppers with a hefty £200 or more. Tesco Clubcard offers more than 100 Reward Partners, with Clubcard vouchers worth up to triple value with some of them, meaning Clubcard members could be sitting on even more value when it comes to rewards. The Tesco app is the easiest place to keep track of all your Clubcard coupons, vouchers, points and rewards. It is quick and easy to join Tesco Clubcard, with more than 24 million UK households now including a Clubcard member.
