You should think about the magic net gain. You can not just buy games for 40$, there must be buyers of used games. These don't show up in your equations. There is only so much money people will spend for games, you can not create more.
I am not saying that Dawdle might not be a better deal for the end consumer. Certainly lower margins means cheaper games means more games sold. But I don't think GameStop are crooks, they simply have an alternative business model. They might be more expensive, but in exchange they offer a different service (guaranteed prices, no hassle with online selling of your game). I don't know GameStop or Dawdle, btw.
