You really don't think Jeff wants to provide us a way to save the most, now do you? These discounts and credits are only to get us to buy more stuff without thinking. Oh look, a $10 credit, never mind all the gotchas, let me buy something. Its all about the marketing. Its always been all about the marketing. It will always be all about the marketing. Just look at the Kindles. I bet 75% of the features Jeff pushes onto the Kindles are to get us to buy more books and stuff. They could care less about usability features.
