the larger retailers, like amazon, certainly scan and keep the serial
numbers of the devices they ship, which is on the same label as the mac
(to detect fraudulent returns).   i believe this was intended so
providers and installers who want to do mac-based provisioning (such as
cable companies for cable modems) can do it more easily.

i have never seen a mac address printed on the outside of any package i
have received from any shipper because almost all of these devices are
packed inside a bigger box which only has an address label and tracking
number on it.
