Question - Experience w/ Amazon Instant Access?

Hope someone here can help me w/ this. I would like to list a lot of digital products (e.g. PowerPoint presentations) on Amazon thru Amazon Instant Access.


I came across this article published by Amazon, but can't find any other reference to Amazon Instant Access:


https://developer.amazon.com/appsan...Items-for-Your-PC-Mac-or-Web-Based-Applicatio


Does anyone have experience w/ this or can point me in the right direction? Thanks.
