Archie: Years ago, when the internet was very slow an unreliable, large data transfer was unheard of. I was working with a guy at Falon Naval base in Nevada on some computer work. It involved a box of 3 inch floppy worth of data. He would need my work ASAP and asked that I send it overnight. Each time I did. It would never arrive overnight, but would promptly be there the 2nd day. I always kept my receipt. I sent packages to him 2 times a month for 6 months, each time paying for the postage with the refund for shipping of the previous shipment. After 12 shipments, each arriving 2 days later, I had never actually paid for any shipments except the first one, and after the last shipment I got the cash back. Later they discontinued overnight to Falon, but continued 2nd day air. The post office must have been a long drive to the Naval Base........ LOL
