If you can't order online, and you're still looking for a copy of Notum Wars in a store, try calling a Babbages store if you have one in your area (the same people who run www.gamestop.com).
It seems that Babbages/Gamestop are the ONLY company in the Atlanta area who have received any shipments of Notum Wars (or have even heard of it) and they may be the only company who got it in your area too!
You can check their website at www.babbages.com or www.gamestop.com, search for Notum Wars, then check the store availability.
One warning though, I was told they will not reserve a copy for you if you call the store, so if they have it when you call, go get it.
