All of the above.. Or have the seller set up the shipment to be held at your nearest FedEx location if it's open until well after you get off work. That way the box will be sitting, undisturbed, inside the building and you just pick it up.
I've done this for customers before who could not be at home early in the afternoon.
How does the seller set that up? There's a FedEx location right down the road from me.
