Hello, Can someone please tell me what the best script to create a store that let the visitors make the purchase from my store without leaving it and go to Amazon?
Try amazon associate script - free, built-in shopping cart, "add-to-cart" real-time e-mail report, "checkout" real-time e-mail report, available for 6 amazon locales (US, Canada, UK, Germany, France, Japan). To download visit my signature's link.
Amazon associate script is alright but what you end up with is a cheap looking website that is similiar to all the other amazon sites out there. I would use WP Shop Builder to create amazon sites that stand out.
You can integrate an amazon astore into your site. It can be customized with some knowledge and effort.
Have you look into this yet? Amazon Affiliate Script is use to this demo site : buydigitalcamcorders.com Code (markup):
