Help with caregiver discount card

Hello to everyone,
Does anyone know of some kind of concession card for full-time caregivers or a method for concession?
NHS staff reductions would be something very helpful. In weekly stores etc. It will be very useful to discount and take advantage.
Thanks for your answer…
