I also primarily have paperless billing and pay bills via autopay services or online, so mail delivery isn't as important to me as it used to be.
However, the idea of loosing USPS Flat Rate services is chilling.
I don't consider myself a "lucky" person. I seem to commonly get in the slowest line or happen to be there when someone, ahead of me, is taking a length of time beyond reason. However, the Flat Rate services have saved me a bunch of time and $$$ relative to UPS or FEDEX. FRBs have arrived badly damaged but I attribute that to poor packaging. Unless the box has been pierced by a fork truck, shows tire tracks or some other outrageous violation, I consider any lost or damaged contents to be the fault of inadequate/incompetent packaging.
Regardless, it sounds like Dave is getting a raw deal and I hope he will eventually recover his lo$$.
