I don't understand why some authors/publishers choose to list their books for full price in the Kindle format. Are there really that many readers willing to pay another $8 for something they've already got sitting on the bookshelf? The author I was looking at today is Anne McCaffrey. Books that have been available for 25, 30 or more years and can be found used for a penny can't be that tempting to the masses just for the convenience of an ebook. Oddly, I think they would find quite a few willing to spend $3 or $4 and the profits from that would be significant.
Today, though, I'll be pulling my old copy off the shelf to reread.
