Buy it NOW!!
It occurred to be that there's really no reason, if I have Trang at 99 cents, not to have it on Barnes & Noble directly (I'm also letting Smashwords populate the book to there so I can make it free when I want to). I changed the price to 99 cents and republished it--a simple matter of clicking a button, since it was up there before.
But I managed to screw it up, and when I went looking for the link to make a Facebook ad, I realized that the price was 99 DOLLARS.
Yeah, that's likely. I've changed it, but you know, if you hurry....
