A supermarket is organising a treasure hunt to keep children on their toes over the holidays.

Sainsbury’s store in Darkes Lane, Potters Bar, will hold the activity as part of its ‘summer sorted’ campaign.

Younger shoppers can pick up an activity pack with a checklist of all the characters they need to find in store while they shop.

Families can also enjoy a reduced entry prices at attractions across Hertfordshire by claiming Nectar points in store.
