Your Amazon script looks very interesting. But the information on your website is not very extensive. For now I have five questions:
1) How do the products come into the categories? It seems to me that one can only specify a whole amazon category to add and limit the products via filter options ("Amazon Search Index" and "Filters").
2) Where does the content of the product pages come from? Unfortunately I wasn't able to try out on your demo store, since changes made in the backend had no effect on the frontend.
3) Is there an option to add further/unique content to product pages? In the demo installation it seems that the concept of the script is to gather some content from Amazon. But I didn't find an option to edit products to add further content. And in my opinion the content on the product pages of your demo store (i.e. on this page) is quite poor.
4) If one buys your script, do you deliver the complete, unencrypted code?
5) What are the conditions of your Money Back Guarantee?
Thank you very much in advance.
