My main goal is to profit while addressing a market I feel is under-served. At the very least, I planned to shoot for a $9.99 or less price to get the higher royalty rate on Kindle (and to not looked overpriced versus other books in the same eBook marketplace). I notice Rework is $9.02 on Kindle; does this pricing have anything to do with the Kindle Marketplace dynamics? So, essentially, I'm planning on writing eBooks that I would sell as PDF/ePub on my own site or in a marketplace like TutsPlus, and also list the same eBooks in the Kindle and other eBook marketplaces. I'm hoping to fill a need I see, as well as take advantage of the increasing popularity of eBooks and eReaders in general. Just like the iOS store, there's a bit of market advantage to having a lower price since it gives your item more visibility. My idea is to make books that are somewhat small (~150 pages or 10 short chapters), but a good value for the size. Additionally, many self-published eBook writers are recommending taking the prices extremely low, to as little as $2.99 or so just to boost overall sales. I know this isn't the approach 37signals usually takes, but with the above in mind, would you see an advantage to lower pricing or would you stick with a higher price? Thanks again for your time and advice; I appreciate it more than you could ever know! I'm thinking I ought to go ahead and get Rework about now...
