heh, i only thought that it happens w/ Fedex Home Delivery only... we're required to slap those little post it notes stating where at the home is your package.
I'll slap them on the inner part of the storm door, window glass by the doorbell, or right on the side of the mailbox & i usually mark the location as well
i dunno about ground, but @ HD, we are required by management to leave these things at EVERY DR stop (except for the signature required ones)
