Choosing the right AWS certification study material comes down to which exam you're targeting and how you like to learn. This group includes a video course for the AI Practitioner exam, two used paperback copies of the same Cloud Practitioner notes, and a brand-new paperback aimed at the Developer Associate exam. Your pick depends on your exam goal and how comfortable you are with used-condition books.
Quick take: If you're studying for the Cloud Practitioner exam and want to spend as little as possible, the lowest-priced used notes are the entry point. If you're aiming for the AI Practitioner exam and prefer video, the AIF-C01 course is the only video here. If the Developer Associate exam is your goal, the brand-new paperback is the only new book in the group.

Product notes
AIF-C01 Exam Preparation Course: AWS Certified AI Practitioner - Video Training

This is the only video training option in the group. It is priced at $5.99 and covers AI and ML fundamentals, prompt engineering, foundation models, and responsible AI, which are part of the AIF-C01 exam objectives. The course is in English and is listed in brand-new condition. If you want a video-first path for the AI Practitioner certification, this is the direct match.
The catch is its exam focus: the course targets the AIF-C01 exam, so it won't replace review material for Cloud Practitioner or Developer Associate.
AWS Certified Cloud Practitioner Training Notes (USD 5.47)

This 2020 edition by Neal Davis is the lowest-priced item in the comparison. It is an acceptable-condition used paperback in English, with pages that may include limited notes, highlighting, or minor water damage, and the text is readable. If you want to start Cloud Practitioner reading with the smallest upfront cost, this copy gets you there.
The downside is the used status: any access codes originally included could be expired or no longer valid, and the cover may differ.
AWS Certified Cloud Practitioner Training Notes (USD 6.68)

This second copy of the same Neal Davis 2020 Cloud Practitioner notes costs a bit more than the other used copy. It is also acceptable condition and shows normal wear, with all pages present and the cover possibly differing. For a small price increase, you get the same content with a more reassuring wear description.
The still-used condition is the limiting factor: this remains a used paperback, not a brand-new book.
AWS Certified Developer Associate Training Notes: Fast-track your exam success w

This is the highest-priced option at $41.09 and the only brand-new paperback among the four. Written by Neal Davis, it targets the AWS Certified Developer Associate DVA-C02 exam and includes ISBN 9798644678556. Coverage includes development tools, deployment, monitoring, security, and cloud application best practices.
The tradeoff is price and format: it costs more than the other options and is a physical book, not a video course.
Final recommendation by use case
If you want the lowest-cost Cloud Practitioner study aid, go with the cheaper used notes. If you prefer a slightly more reassuring used copy, pick the other Cloud Practitioner notes. If you're taking the AI Practitioner exam and want video instruction, the AIF-C01 course is the only video option here. And if you're committed to the Developer Associate exam and want a brand-new paperback reference, the Developer Associate Training Notes is the one to get.
