Happy New Year Sandy.
Rotation.org doesn't sell any products. The lesson writer recommends a video which you would then need to purchase from a resource retailer. (Vision Video, Christian Book Distributors, Amazon, to name a few.) In some cases, the recommended videos are on YouTube. Or if you're really lucky, you already own the video or know a church which does!
All video recommendations found in the new and improved Video Workshop lesson plans have been "vetted." We look at many before selecting one.
In most public forum video posts, the recommended video is simply the writer's opinion, and in fact, you often see several suggested videos. Check the date of the post's recommendation as there have been some great new videos that have come out in the past 5 years.
When unsure about which one to pick, you can often find that someone has uploaded part of the video on YouTube so you can check it out yourself. OR, you can post a question in the LESSON HELP FORUM to get replies/opinions from those who have seen various videos for the story you want to teach.
