Simos 300-209!!!

Am I missing something here? The study guide for the SIMOS 300-209 exam is priced at $887.12 on Amazon while the SISAS study guide is priced at $43.99. Any major detail here that I'm missing? decided to read the actual text for study instead of going through INE.com videos where you have to pay a minimum of $399.00 for three months access.
