Right - you're making our point. When GS buys a used game for $20, they re-sell it for $40 (49% margins). That means the value of the used product is $40. If you can sell it for $40 on Dawdle, a new game only really costs you $20.
That means your $100 in purchasing power gets you five new games: the publishers, developers, and retailers only benefit when you buy new product. We're trying to show them how used games can work in their favor if you cut out the GameStop middleman.
Edit: as for the uncertain price, we're working on it. With our StandingOffers, we might be able to find people willing to guarantee you $30 or $35 up front.
You should think about the magic net gain. You can not just buy games for 40$, 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.

As an example of how that works, right now, I'll pay $25 for a platinum Wavebird (http://www.dawdle.com/product.php/wavebird-wireless-controll...).
