You are referring to the retail price; set by Activision, the Publisher.

But we all know you get the game cheaper.

In UK you pre-order at Tesco with 20% off.

So when you pre-order instead of buying at high street retailer you will pay $100 for MW3 +DLC

you are forgetting that you also get the dlcs for free too.  for black ops there were 4@$15 each is $60 + $60 for the game +$50 for elite and you are getting $170 for 100 plus the metal case. 

My Gamestop told me they weren't taking pre-orders any longer on the hardended edition. I think they realized their mistake when I told them OK, I am going home to do it via Amazon lol. Sometimes the employees can be rather foolish and attempt to try to make their customers regret waiting or not pre-ordering something (I have seen them tell people they don't have enough copies of something on launch when they have a giant box sitting there at their midnight release). I am guessing this is one of those times, their loss . But just fair warning that they might tell you that as well...That is what Amazon is for though.

Managed to snatch the last hardened edition from my local game store today, the guy behind me look pissed.

Got my Hardened Edition for $80 from BestBuy.com w/ free site-to-store shipping. 

I'm hoping they'll tell to go pick it up at midnight but if I have to wait a few days then so be it.  Getting all the DLC for $20 will be worth the few days wait.
