Finally something for existing users
Existing Tidal users can get 20% off their subscription price (hi-fi or premium) when you go to the cancel your account page.
From the web browser click on the 3 dots/your profile icon on the top left and then manage account. Then go to subscription and select ‘cancel my subscription’. It will then give you the option to redeem a 20% discount offer for 3 months.
Makes it £7.99 for premium or £15.99 for hi-fi.
