The wife used to work for Grainger HQ in their securtiy/loss prevention department.

They had a ring of assistant managers that were short-listing meters (ordered 4 received 2) or listing them as broken or otherwise "damaged in transit", then selling them on EBay for a fraction of the normal retail.

They were caught (IIRC) because one of the perps listed the serial number in the auction, and it was traceable to one of his sign-offs.
