So far this year, even that meager gravy train is over. I've only see sales in $0.99 range.
Running ads via Amazon, I've saw increases in give-aways, but no increase in sales. Annoying.
At the end of last year, for some inexplicable reason, I kept selling book on the Nook. That ended solidly on Dec 31. $20. I won't complain, but I am annoyed.
I ought to figure lots of things from this, but just about anything that I figure is based on poor information.
What I can say is that the covers aren't competitive enough, the blurbs aren't competitive enough, and the samples aren't competitive enough, not because I did a bad job improving them last year, but because those are the three things that matter most.
The good news is that I've already paid for my cover images out of last year's money. If I spend no money, I make a profit. Then again, if I don't spend more money, I create no more opportunity.
