There are three reasons I sold exclusively through my own site: - Stores like Amazon and iBooks limit the price you can charge. iBooks limits it to $15 for the book, Amazon radically changes the royalty payments if you go above $10 (or so). I want to charge premium prices, so those audiences wouldn't work. - Selling through another provider means that they aren't my customers. I don't have contact information for follow-ups, other sales offers, or anything else. Owning the customer list is really important to building a sustainable business. - When I sell through my own site I keep about 95% from every sale. If I sold through the iBooks store I would only get 70%. I would be willing to accept a lower percentage if it meant I was able to build my customer lists. A final thought is that I've seen people put all their effort into creating the product (whether it is an app or an eBook) then put it up on the store, just expecting it to take off and organically get sales. By selling through my own site I was forced to do all the marketing and promotion myself. Since that is a skill I am still developing, it was important to me. Good luck!
