Better safe than sorry
If you live alone and know that you will not be home for deliveries, ask
your dealer or shipper to address it to
Card for Pick-up
then your address.
This way CP will not even attempt a delivery but will leave you a notice
to pickup. Once you have that, your CFO will issue your ST-ATT on the phone.
Do not gamble, hoping that you'll be home. I've had a couple of (against-signature) parcels left at my doorstep (in an apartment building.) The postman though he was doing me a favour. Luckily those two parcels were books and CDs but my apartment is right next door to the elevators and every single (or married) Tom, #### and/or Harry could have walked away with the parcel. And the strange thing is, that when I tracked these parcels, they were shown as delivered and I was shown a sample of my own signature (not in my handwriting.) But CP achieved the miracle of having me at two different physical places at the same time.
