Exactly. Amazon isn't providing storage and delivery nearly as much as they're providing eyeballs. (The "hot list" is a self-fulfilling prophecy -- you don't need to be incandescent to make the list, but being on the list tends to increase sales -- as are recommendations.) If you think you can drum up the eyeballs yourself, then go for it. Just be prepared for vanity press results if you're not all over the marketing.
