I wouldn’t be surprised if they stole credit cards, bought LEGO with the stolen cards (drop shipped somewhere other than the card owners’ home addresses), then resold the goods at prices low enough to guarantee sales but high enough to make killer profit margins (obviously, since their expenses are nearly nothing.) I’m pretty sure a Fire Brigade I got on eBay a few years ago was a case like that… I didn’t know at the time (because it was still available so the price hadn’t skyrocketed, so I thought I’d just found a deal where someone had gotten it on sale or something…) but yeah, the seller’s account got shut down…
