The gig used to be if you were a scammer with a stolen CC number, you placed a small order shipped to the card's billing address first, then once that went through they could more easily order stuff and ship it elsewhere (to themselves) without triggering a fraud alert.
Yeah, I've heard of that one, of course. And I've heard of the one where you receive a shipment without being charged. I've just never heard of getting charged for a package and getting that package. The stuff is roughly worth what I was charged (just by my estimation). I'm lucky that I have my credit card connected to my phone so I know whenever there is a charge.
