Note: I have only tried this method on Spotify Family Plan owners, you won't get anything from normal premium useresThis should work for UK/FR/AU users

1) Head to this link: https://www.spotify.com/au/googlehome/redeem/
2) When you get redirected, copy this link and open it in incognito, this would save you time on the ReCaptcha
3) To check if the code works, you have to add one of the Google Home Minis to the cart and click on checkout
4) Once you've reached the checkout page and you see that the amount does not change, try copying the promo code from the URL itself
5) The URL should look something like: https://store.google.com/au/config/...=GS102131&promoCode=B-ND7UHU3Z2M2HTS4EF3VZPSR
6) In this case the promo code is: B-ND7UHU3Z2M2HTS4EF3VZPSR
6) After applying the code, if the code works, you should see the amount that you have to pay go to 0
Warning, use different names and different cards if you want to send a few Google Home Minis to the same address[/hide]
