Charlie, do you just leave your packages by the mailbox and your postman "knows" to pick them up?
Yes - raise the red flag, put in mailbox if it fits, that's what they do... too easy, convenient, and economical. I've also stacked them by the mailbox with flag up, no sweat. You'll know you got it really bad when you intercept the mail lady a couple hours before she gets to your house for the toy car delivery.
I stopped at the post office today. The mail clerk grinned when I said, "Why would people complain about US Mail when for only a few dollars, the mailman will take a small package anywhere in the United States for you in just a few days time?" I still remember sending my first international letter to a penpal in West Germany for a mere 50 cents... priceless! If it weren't for eBay and their USPS deal, the USPS would close many more offices, or deliver five days, not six.
Take it while you can...
