There's another potential problem with AMAZON shipping that I ran into once. Ordered something from them and got a Tracking Number for the item. It never showed up and the Tracking Number was eventually deleted from the shipper's web site. Turns out the package was denied by the shipper because it was poorly packaged and returned to AMAZON who didn't process it correctly as a return. Their records indicated the item had been shipped, but they were unable to verify receipt of the item thru the shipper's Tracking Number. AMAZON eventually shipped a replacement, but then asked for the return of the original item and if I didn't return it they'd charge me for both items. Thankfully the shipper had enough information in their database to explain the whole story, but it wasn't accessible from their web site. That was my last time buying anything from AMAZON.
