Bought the ghost recon game gold edition before I noticed the special for 15,000 point deal on

If you purchased it digitally and/or before March 7, you would not be able to receive those credits.

The promotion only rewards 15,000 for the Gold Edition of Ghost Recon AND it had to be purchased as a physical disc from microsoftstore.com to be eligible for the offer. If you did all of that then it takes up to 15 days after the title ships before the
points are eligible.

If your purchase was not a physical disc from microsoftstore.com AND the gold edition then it would not be eligible for the promotion. If you bought a different edition from the microsoftstore.com then those have different values you can find here: https://rewards.xbox.com/faq/#=ghost_mar17

If you preordered it digitally, it would have counted towards the Games on Demand punchcard offer. You would need 2 other eligible purchases in order to complete that offer and receive the 15,000 credits. If you bought it after release, it would have counted
towards the "Simply Rewarding" offer for 6,000 credits as long as you activated the offer before purchasing. But the Ghost Recons offer was only eligible for physical purchases made from microsoftstore.com
