How Much Does Amazon Pay for Paperback Books?

On average I know across the nine different books Luca what sort of an average month in terms of total royalties look like from both Amazon and Gumroad? About 2000 euros so a little bit over $2,000. Oh that's great and then is it skewed more towards Gumroad versus Amazon like is one more lucrative for you? It's roughly 5050. And there is an of course is because Gumroad I get 90% of royalties on the ebook whereas on Amazon you get roughly one third.
