A lot of confusion going on here. Let me help clear it up:
There are three separate promotional deals going around right now that are each essentially the same thing:
1. A B1G1 unique e-mail code that was sent out to people who have already previously preordered 1 PS4 launch title.
2. 1 Free Game unique e-mail code that was sent out to people who have already previously preordered 2 or more PS4 launch titles.
3. A B2G1 deal open to everyone, using promo code GR8TNESS, on select PS4 launch titles, which DOES NOT go into effect until 12 PM EST on Tuesday 11/12.
Amazon is essentially matching Target's deal for PS4 launch titles. I suspect that they e-mailed the unique codes to people *as a reward* for already preordering 1 or titles with Amazon before the actual, open-to-all promo was slated to start.
This is a GOOD thing. It is fair to everybody.
Please understand.
