Not surprised. I also seriously doubt the sales of her book. When I used Jungle scout to check sales, I see a very consistent amount of sales of around 900 or 1000 per month average since April 2019(as far back as it lets me see) Amazon is also 50% of the print book market, so I can't figure out how she's sold 10+ million books when she's only selling less than 1,000 per month on Amazon. And despite 5% of the adult population in the US supposedly having bought this book, just like the coronavirus, I've never met anyone that actually had it.
