Hi,
Not sure if this is what you want, but one thing you can do is put some Amazon links (using the [amazon] shortcode) in the body of the post. The plugin will remember all the ASIN’s you have used in the post content.
Then create a Text Widget in the sidebar with the content:
[amazon cat=local&wishlist_type=random&wishlist_items=5&template=thumbnail]
This will show a list of 5 random thumbnails of Amazon products featured in your post.

Hrm so maybe if I used that method with some custom sidebar plugins I could get what I’m looking for. Will test some things and let you know.
