Amazon MWS submitting price setting feed
===

I've been looking at the documentation scratching my head wondering how to submit an XML feed which would do something as simple as changing the price of an inventory item

I've been looking at the example XML feed that they give as shown on page 15 in this [link][1], since this is the only example I have found I don't know how to go about inserting or editing products in my sellers inventory. can anyone give me any tips
