Automation of product feeds for Amazon

Hi everyone

I am hoping someone can point me in the right direction, I currently have 3 suppliers who all supply the same variety of products and provide a FTP server to generate a CSV feed of their stock list.

Currently I manage my products manually and browse each individual supplier and monitor price changes so I can update my inventory, is there a way to automate this on seller central so it always has the cheapest price and to update current stock levels accordingly?

Kind regards

Lewis
