Set a fair selling price. Many new authors make a mistake when selling an e-book in digital text format for the Amazon Kindle. That mistake is too high of a price. Remember that Kindle owners paid over $300 for the device. Although a good price for the technology received, it is a lot of money. Why would an owner pay over $300 and then $20 or more for each book? Don't undersell yourself, but know that the best selling Amazon Kindle books are in the price range of $5.99 to $12.99.
