Tesco is offering its 19 million Clubcard holders discounts of between 15% and 50% on selected products, including pet food, as part of its centenary celebrations.

Running throughout May, the ‘Clubcard Prices’ will be available in-store and online. To get the discounts, in-store customers are required to tap their card or scan the Clubcard app at the till, while online shoppers get their discounts applied automatically.

Alessandra Bellini, Tesco chief customer officer, said: “Clubcard continues to be the most rewarding loyalty scheme in the sector. As we are celebrating 100 years of great value, we wanted to say a big thank you to our millions of loyal Clubcard customers with special lower prices just for them.”
