title: How to check inventory of another seller/merchant in Amazon MWS
body: <p>I have been developing a web application using Amazon MWS. I want to add a feature in my application that is, to track the inventory of seller/merchant. i.e. if we are 'seller A' and competitor is 'seller B' we need to see their inventory on our application.</p>
