That's a weird thing to see.
I've violated absolutely every rule in terms of generating sales: there's no description, no cover, it has a relatively high price ($9.99). Dropping the price makes it unavailable for 24 hours. And it looks like the delivery cost of .02 from each sale is deducted from my royalty. If nothing else, this has been a great little exercise in answering a bunch of dumb questions I had about the process.
