Tesco has issued an urgent alert to its 24 million Clubcard members to check their accounts before Sunday, as vouchers worth £16.5 million are set to expire at the end of this month. The vouchers, which remain valid for two years, must be redeemed before midnight on 30 November.

Members can use their vouchers in-store or exchange them for double their value with more than 100 Clubcard reward partners, with several attractive new deals now available. Among the latest offers is Tesco Tuesdays with Cineworld, where Clubcard holders can secure cinema tickets for Tuesday screenings for just £5 (equivalent to £2.50 in Clubcard Vouchers).
