My best book is 102 and priced at under $13. I have found similar books on here same number of pages but priced at over $25. Not manuals either but paperbacks. What about kindles what should pricing be here you think? I think that these are really overpriced. I know of one person who wondered why his book didn't sell and it's priced at $27 for an 82 page book.
