Oh wow, so the deal is actually 0% revshare. And I thought I was a weak negotiator... :D

Well congrats then.

That’s not exactly true - as an Amazon affiliate you do see the exact items purchased under each of your specific tracking IDs, as well as the price it was purchased for, category and device group it was purchased using (desktop, tablet, mobile). This also includes any purchases the user makes in a 24 hour session of browsing after clicking your referral link to Amazon.

I’m unsure how many tracking IDs you can create in your account, and as far as I’m aware and can tell, you cannot pass specific UTM codes or other identifying information along with a click to Amazon that is passed back to you on the reporting side. Meaning, you could track users you send to Amazon, and where you’re sending them, and you can see outcomes, but Amazon only provides the tracking ID back to you as a reference (this ID is meant to be used on a site/channel wide level, but as I mentioned above could possibly be abused depending on how many you can create)
