So I stumbled upon this. Supposedly Best Buy will be selling them on Friday. I'll be calling my local store right when they open on Friday to have them put one aside for me.
Nah, you can add it to your cart and select "Buy an Unactivated Device", and the price changes to $699 (for 32mb.)
EDIT: Oh, wait... That option is under "Current Sprint Customers." Maybe you are right.
EDIT: But then again, I went through the checkout (until they said it isn't in stock) and it never said anything about having to be a Sprint customer.
Policy is only to price match Play Store, etc. if it's in stock at the time.
But $50 off wouldn't even require an override, and people are generally clueless, so you could likely get away with it.
