Books are expensive, but some books are a whole other universe of expensive. There are generally three reasons for that. I don’t think I’m giving away any deep, dark secrets, so I’ll explain why some books are so expensive on Amazon. Like, $800 expensive, sometimes. Better yet, I’ll also explain how to know if the book you’re looking at is overpriced, or if it typically does sell for those high prices.
Some books legitimately are extremely valuable and expensive. But sometimes low-demand books get caught up in price wars that drive prices up due to short supply.
