If you only need the buying answer, rental is the cheapest route by a wide margin. The current print copy is still worth considering because it sits below Cengage print, below the sampled used floor, and only slightly above the current eBook price, which makes ownership reasonable if this subject will remain useful after one term.

The decision here depends entirely on time horizon. Rental clearly wins if the course is the only reason you need the book. The print copy becomes more interesting because it is barely above the current eBook price and still below the used and official-print alternatives. That gives ownership a legitimate case for students in counseling, gerontology, psychology, or helping professions who may return to the framework later.
What this book actually teaches
Adult Development and Aging covers adulthood across cognitive change, health, work, relationships, loss, caregiving, policy, and the broader social realities that shape later life. In practice, this is not only a lifespan theory book. It is also a way of thinking about aging in context, which is why it can remain useful beyond a single developmental psychology course.
That continued relevance is the real argument for print. If your need is narrowly academic and short-term, rental is the disciplined financial choice. If you are moving into counseling, gerontology, social service, or other practice-oriented fields where adult development frameworks return later, the current paperback is priced well enough to justify keeping a copy.
Who should buy print and who should not
Choose rental if you only need low-cost access for one course. Choose print if you expect to reuse aging and adult-development material in later coursework or field-based practice. The current paperback is not the cheapest route, but it is competitive enough to make ownership sensible for the right reader.
