Here is how it works:

⭐ The parent who hasn't used CSS Activities before will make their booking via our form and type the full name of who recommended them in the 'Refer a Friend' section of the form.

⭐ The 50% will only be applied to the new booking if the parent has not used CSS Activities before, in any location.
