As a frequent Kindle fiction buyer, I have to say that I do usually pay attention to low prices like that, especially if I don't recognize the author. I've found that when gambling with Kindle fiction, the $1.99 and $.99 books are usually that cheap for a reason; poor plot and many typographical errors. That's a factor at least for me, when buying fiction from an author about whom I know nothing; perhaps the sales were mostly from people who didn't recognize your name?
