Preordering a game sold by Gamestop on BN.com...?

So, I've got a $15 BN.com (Barnes & Noble) gift card that I want to use on preordering Halo Reach that is being sold on the site by Gamestop, but I'm a unsure about ordering it for one reason: Will I get the preorder bonuses since I'm not ordering directly from Gamestop?
