Mondelez has made Valentine novelty gift range Say it With Cadbury a year-round treat after it proved especially popular with shoppers aged under 35.

The chocolates come in 48g or 180g packs as heart-shaped milk chocolate pralines branded ‘With love’, and flower-shaped pralines in a ‘Thank you’ box.

Mondelez is also launching 50p price-marked packs of Wispa, Crunchie, Double Decker, Crispello and Maynards Sour Patch for January.
