I am working in France to make a cultural social network where people will share their cultural taste. I'd like to use the amazon Product Advertising API in order to give the visitor the opportunity to buy DVD, books, ... they talk about on my website. I don't want to just make affiliate links because I need that the visitor stay on my website to continue his experience. Amazon Product Advertising API say that we can use their services in that order and visitors have to go to amazon only for the checkout and could make a cart with different products without leaving my website. I'd like to know how much work (time and money) it represents to implement Amazon Product Advertising API in that way on a websites which will have around a 500 000 differents pages of cultural work which could have amazon product to be sold. Is there some technical limit with that API for this project.
