Yea, but from Amazon only. I don't have to pay til it is delivered, it gets delivered for free, and if they run any specials between when I preorder and the game comes out I get those too. So far I've picked up a $10 coupon, and over $15 more off games.
Also, I only really preorder Nintendo 1st party games as those won't drop in price for years anyways, so it's just a matter of if I have the money now or not.
