I pre-ordered mine from Best Buy. 
Gamestop, just because it’s the most convenient.
Futureshop. All the other stores in my area had run out of Limited Editions by the time I got around to preordering.
Since this topic is Halo 4 related, I’ll be moving it the Halo 4 section.
Also, I pre-ordered mine from Amazon.
Gamestop, it’s right behind the corner.
Microsoft Store, since you get Pulse skin and a $25 gift card which I will use to get the map pack DLC.
Amazon, and Mightyape
I liked their exclusives.
Game cause i love the pre-order artic blue skin they got!!!
Gamestop.
GAMESTOP. most benefits for pre-ordering 
Gamestoppage…
Gamestop since its the only store around. Also you do get the pre-order bonuses with LE right? I looked at the game on their site and the bonuses were not listed on the LE versions page but they were listed on the standard editions page.
Gamestop, five minuets away from my house.
Walmart because it was closer.
Im al about free stuff and Futureshop is giving out a free steelbook case with the pre-orderer so Ima going there. I usually get from EB games but they give nothing.
Limited edition from EB Games NZ. Five pre order bonuses hell yea! (Including BR artic skin, you jelly?)
Nowhere. Pre-ordering is beyond pointless in my area, I’ve never seen them run out of a game as big as Halo. I’ll just go to Best Buy the day of release and grab a copy off the shelf, and that will be that. Same thing I’ve done with every other Halo. (except Reach cause I wanted the LE)
Amazon, because i’m gonna dress my spartan up like spiderman!
