For students using a zyBook in a college or high-school class, we automatically provide a discounted price typically between $58 - $90, depending on what content is included (many instructors combine content, use add-ons, etc.).
For non-students, most zyBooks have a regular price of about $195.
The price appears on a zyBook's home page if unsubscribed. This article explains how to get to a zyBook's home page.
