What's up with that? Selling for full-price of $59.99 on Release Day, but you can trade it in for $11.75.....That's like buying a $60k car and the trade-in value for it drops to $11,750 once you drive it off the lot.
They do it on purpose. That way no one is tempted to "break" street date in some nefarious way in order to get higher trade in value. I've seen it with a lot of games on Amazon. Within the next couple days...it'll go up to 30-ish.
