The author is a little deceptive, it wasn't a "Best Seller", it was a best seller in its category. Each category has its own best seller, and apparently the category he chose (Transpersonal Psychology Movements) doesn't have a lot of sales.
The deception is him telling people he's a "Best Seller" when really he's "Best Seller in Category." And frankly, Amazon's styling encourages the deception.
