I didn't per-order my S7, I just went to my local T-Mobile store and bought one. I still got the Gear VR as part of the promotional deal. Since the stores are supposed to have them in stock the same day as they promise to deliver one to my home, I'm not inclined to be sitting around waiting for the delivery guy who always seems to make it thirty seconds before the end on the delivery window. Is there some other reason I should pre-order?
