I'd love to get cards in the mailbox notifying me of something to pick up at the post office. 5 out of my last 6 deliveries had no card left and I only found out they were waiting at the PO by checking the tracking numbers online. For the 6th delivery (last Monday) the postie handed the card to me personally - he had my package in his bag but couldn't give it to me since he'd forgotten to bring his 'signing gizmo' - therefore I couldn't sign for it and had to go to the post office next day to pick it up.   Great service - NOT!
