If I didn't see it with my own eyes I would have rated it at least 4 stars, maybe 5 for a free plugin.
It does everything it says it does and I love it. It's very well written.
Plugin author has his own Affiliate links built in so it sends to his affiliate code under your API. I had to edit out his links which are in the amazon.php file and replace them with my own.
Use this with caution and MAKE SURE YOU EDIT OUT HIS LINKS!
Now that I have done that it works beautifully.
