I don't have ebooks on the platform quite yet but I should have them running before the end of next week, alongside the "No Amazon" filter that will ignore Amazon and any subsidiaries from searches.
Curious, since I didn't look are you hoping to (or are you already) earn some side income to fund this going forward via affiliate links?
I say this knowing full well, maybe some of the results wont get you any income, but the ones that do might be worth keeping in results. Side projects eventually burn a hole in your wallet.
