[Criteria] Sales & Royalty Reporting [iBookstore] A Apple’s reporting system is updated daily. Reports can be viewed its iTunes Connect website as well as in an extremely well designed iOS app. [NOOK Store] B B&N’s reporting system is minimal but accurate. [Kindle Store] 
C Amazon’s reporting system is inconsistent and confusing, although it does have up-to-the-minute sales figures. Amazon’s staff does not reply promptly (or at all) to sales/royalty report questions. Reports seem to indicate book sales at unauthorized prices, making me wonder whether Amazon is ripping me off.
