Spotify through PayPal is offering 3 months free again. It won’t appear in your offers on any Spotify offer page either.
Google 3 months Spotify trial PayPal and you’ll get directed to Spotify’s website, make sure you’ve selected PayPal and create a new account.
I signed up with a new email but a previous credit / Amex and it worked fine. See screenshot.
Happy listening - although I do prefer Apple Music, but you can’t be free!
