How to Get all Size Variants using Amazon's Product Advertising API
===

Right now, the XML response that I get from the API contains just the size of the clothing corresponding to its ASIN. For the case of ASIN `B0069NZPHA`, the `Size` is `Small`. However if you were to visit its [detail page url][1], you can see that there are 2 sizes, Small and Medium. 

Is it possible get all the sizes related to a particular ASIN?
