I guess I just have no faith in Delivery Confirmation since I had an experience with one P.O. several months in a row where they did not scan something I sent when it arrived. I wrote letter after letter and still they didn't scan it-this was something going every month to a P.O. box for awhile and I needed that confirmation. I got my money back every single time because they took money for a service they didn't provide. I know the item was received every time, too, so it should have been scanned. Technically, to take money for a service you dont intend to provide is fraud and told them so at the Charlotte, NC P.O. that fell down on the job. That is why I hesitate to even pay for that service with eggs I send out. I don't think it makes any difference one way or another. Either they get there or they don't. If they dont, no need to look for them because of the "expiration date" of hatching eggs.
