The Amazon PAAPI is "interesting" because to even access it, you need to have 3 qualified sales. But... I wanted to use the API to create a website where I'd post the affiliate links on. It's a chicken-and-egg problem. That's why I went with eBay.
Yep, I don't have much experience with affiliate programs (I like to build more SaaS-like apps[1]) but from my research Amazon have gotten really stingy circa 2019. Happy to see an alternative.
[1] I didn't know about the 3-sales precondition either. I guess some people bought albums on Amazon on my other music-related app.
