If you only need the buying answer: the current paperback listing is the strongest clean route in this snapshot. It is lower than the sampled rental, much lower than the sampled Kindle price, and far below the sampled new-print comparators. For a methodology book that often becomes more useful later, print is the clear value route.

What this book actually teaches
Single Case Research Methodology is a methods text about design logic, visual analysis, baseline structure, intervention effects, and the practical interpretation of single-case studies in special education and behavioral sciences. The book matters because it helps readers understand why designs work, not just what the designs are called.
That is exactly why methodology books often grow in value after students first struggle through them. Readers come back later when they need to interpret graphs, plan applied studies, or make methodological sense of work they did not fully master the first time through.
Why print is the right fit here
In this snapshot, the paperback is not just reusable. It is also the cheapest clean option sampled. When the keepable copy costs less than both rental and digital reading access, the ownership case becomes straightforward.
I would lean strongly toward print for students and practitioners in special education, behavior analysis, and applied research who expect to return to single-case design logic later. The only real reason to avoid ownership would be dependable library access plus no realistic need to revisit the book.
