M&S offering free Big Daddy chocolate bar for Father’s Day

Members of the supermarket’s ‘The parent hood’ programme can claim a Big Daddy chocolate bar before Sunday, June 21.

The scheme was launched back in 2024, aiming to provide a network to new parents, from pregnancy to two years old.

Members have access to exclusive treats and helpful advice, as well as weekly parent & baby mornings at M&S Cafes.

In August 2025, the supermarket revealed that 230,000 people and counting had signed up for the loyalty club.

Shoppers who are part of ‘The parent hood‘ will be able to claim a free Big Daddy Bar, usually priced at £8.50.
