Do I need to purchase Edition 3 if I already own a previous edition?

Not necessarily! If you already own a previous edition, you can absolutely continue using it.

Edition 3 includes new sections, expanded resources, content updates, and a refreshed design, but that does not mean you need to replace your current Nursing School Success Bundle.

And if you own a physical edition with access to the Bonus Portal, you already have access to the newly updated Bonus Portal and its resources.
