This seller sounds terribly odd. In some descriptions they say that they are "dying inside" (severely ill?), yet in others they claim that "debt has got me in a stranglehold."
If they're going to try and elicit sympathy, at least they could get their story straight...
I would guess that they had images of these cels uploaded somewhere else and couldn't be bothered to look up the sequence numbers before posting to eBay. Either that, or these cels are listed on some dealer's site...and this person will only inquire to the dealer after someone asks THEM. *sigh*
