I use C & S for both Ebay items and our online bookstore.  I find it very convenient, but I've had more parcels go missing since using this service than previously.  I no longer indicate on the postage label what the contents are, or use code that wouldn't make sense to anyone else.  I am convinced that some items have selectively 'gone astray' because of what they were - within the Aust Post system.  ie, they were marked as delivered, but clearly weren't.
