how do people make money?

That isn't card theft. Thieves aren't getting rich selling diesel jugs for under $20 when you can find 'em on the side of the highway. Card theft guys are buying TV's and Apple stuff and gold bullion off eBay.
Porch piracy maybe, but the guy is good, three-day shipping a jug that invoiced out literally the day before it arrived.

I'm telling you, those aren't what's happening here.

OP, call AZ and ask 'em? I know they got phones...I used to answer 'em.
