Money Saving Expert is warning all Tesco Clubcard holders that in just under three months their points could become considerably less valuable.
Millions of UK shoppers regularly use the loyalty card on trips to Tesco, for anything from a big shop to a meal deal. The points can then be "spent" in store, or converted to vouchers to be used elsewhere.
Customers who opt to swap points for a voucher with one of Tesco's "Reward Partners", such as Pizza Express and Legoland, currently triple the monetary value.
