From the 21st August until 2nd October 2019, Sainsburys were involved in a campaign to promote healthy eating and personal development. The theme was "Unlock the Hero in You" and it included lots of challenges and advice about nutrition, exercise, and teamwork. This recruited various Disney, Pixar, Star Wars and Marvel heroes, and put them on a range of 144 cards, designed to encourage children to start collecting. There was also an exclusive collectors album costing £2.50, and including two packs of cards. Customers got one free pack of four cards for every £10 spent in store or online and "booster packs" were sold for 50p. To encourage healthier eating, extra packs were often given away with healthy food.
The cards were removed from sale on the second of October 2019.
It may have been planned to have another set in 2020 but it fell foul of the pandemic and there were no cards that year.
In 2021 the cards returned, with " Heroes On a Mission", 144 in total, showed how simple steps helped to care for our Planet, and, because they were a Sainsburys product, how to eat well. The cards were free with every £10 spent in store and online but the album was £2.50, though you did get two free packs (each of four cards) for every album purchased. And you could buy additional "booster packs" for 50p. Also there were special events here you got a pack free with selected foods and groceries
They were available from September the first until October the twelfth 2020.
