Get $5 Promo Code after You Listen to a Podcast in Full on Amazon Music @ Amazon AU

So it's pretty much, free money.
I am not sure if this is targeted, because I have searched for this on google. I haven't received an email regarding this promotion and it says I am eligible.

You will have until 23 May 2023 to earn your code by listening to a full podcast episode on Amazon Music.
The code will be emailed to you within 7 days of your first stream and can be redeemed within 30 days of receipt against an eligible purchase of £20 or more.

*I am guessing they mean when you spend $20 or more
