warshawlawI recently sent an E90-1 to a seller for a refund. I used certified mail with return receipt and put the package into our postman's hands. It never made it into the USPS system. The seller claims he never got it, the USPS has no record of it. Our postman is a long-time deliverer and a really nice guy who's handled hundreds of packages for me, so I really don't think he lost it. I think the USPS fumbled.
Confirmations and tracking capabilities are great stuff as long as the package actually makes it into the registry. As one of my friends once observed, the best systems in the world are no match for a minimum wage clerk not doing his job.
