There is no point in buying a Kindle if it's more expensive to read a book. Amazon are keen to point out that the "Price is set by the publisher", so while Amazon & the publishers argue over who get what percentage, the customers get shafted with overpriced books. Use the tags section to highlight any overpriced Kindle books with things like "Kindle rip off", "price fixing" etc. , and don't buy from publishers that overcharge. You could also contact the authors to let them know that they are missing out on royalties because of these high prices.
