Pre-Orders are still available, but I think they will sell out today.
pre-ordering from Amazon doesn't even soft-charge your account. If you rather go with Best Buy they will soft charge, but will drop off your account in a few days. Good way to pick up points.
From What I Understand (In Case People Are Interested) If You Choose To Pre Order Thru BB Online They Charge You The Full Amount Upfront, You Have To Actually Go To The Store If You Wanna Just Put A Small Down Payment
