docs: // This method returns a collection of active usage rate [[SoftLayer_Product_Item_Price]] objects for the current package and specified datacenter. Optionally you can retrieve the active usage rate prices for a particular [[SoftLayer_Product_Item_Category]] by specifying a category code as the first parameter. This information is useful so that you can see "pay as you go" rates (if any) for the current package, location and optionally category.
