Indie Author SOS ~ Weirdness!

So I was checking out the listing for my book, That Fatal Kiss, on Amazon.com (yeah, I was eyeballing the Amazon Best Sellers Rank, which I've been doing daily since I released it in September) (OK, I look at TFK's ABSR several times a day; gimme a break, this is all new to me and I've got compulsive tendencies) when I noticed something weird. It struck me as so utterly bizarre that I squinted, really hard, at my laptop screen (and I do my damnedest not to squint, 'cause I can't afford the wrinkles). I even asked someone at my day job to take a look at it, as I just really couldn't believe what I was seeing. Here's a piccie of The Weirdness (hint: look closely at the pricing in the rectangular box):

Do you see that Used Paperback price, through Amazon.com Marketplace? Someone's listed for sale a used paperback copy of TFK for almost a thousand dollars.

Someone has listed for sale a used paperback copy of TFK for almost a thousand dollars.

Uh...what?

Say what???

Seriously, what the actual fuck? For realz? C'mon, that's gotta be a typo, right? The seller meant, like, 99 cents, probably, right? Right?!

So I e-mailed the good people over at Amazon.com, just asking if that was a legit listing, and was given some canned response about sellers being able to ask any price they want for the items they put up for sale.

Yeah, that's fine, but what the hell did the seller do to that copy to warrant a ticket price of $999.11? Gild the page edges with actual gold, melted down in a vat in his basement? Embed in it some new stripe of artificial intelligence, so that it can do your homework (and/or taxes) for you, on demand? 
Imbue it with such mighty mystical powers that, if carried around as a charm, it'd keep mosquitoes and zits at bay for, like, forever? ('Cause that would be rather impressive, wouldn't it?)

I'm tempted to write the seller and ask her/him to let me know if it sells at that price, just to see if s/he discovers (and owns up to) an error in pricing. 'Cause that's totally a mistake. It's just gotta be. Or a cruel, cruel joke.

Indie (and/or traditionally published) authors of teh Blogosphere: any o' y'all seen some shit like that? If so, did it weird you out? If so, did you do anything about it? Should I be doing something about it??? (Probably not, but this thing's just do weirdly weird that I had to toss in a few more question marks somewhere...)
