When should i receive my 15k rewards points for my ezio trilogy purchase

The credits should show as pending about 15 days after the game shipped. If you don't receive them after that, you'll need to post in the Xbox Rewards Questions forum.

since I am going all Digital can I pre-order it on XBL, and still get the rewards points or have to purchase it from the Microsoft.com store to get the points?

I think you need to order via the MicrosoftStore.com website for that, if they are still doing that offer - but do they sell digital downloads at their retail stores? I did the 15k points when I preordered Just Dance 2015 on a disc; I don't recall having
a digital option.

Btw, do you already have your Rewards page activated? It took them about two weeks to get mine set up initially, and it seems to update slowly. It's only been a week, but I still haven't seen that 15k points dropped into my account yet. Slowpoke.

You should play them all from the beginning, the story is amazing. Playing the Ezio trilogy is something you need to do.

please help, I need to receive my rewards points for my purchases. Thank you.

I also did not receive my point reward for purchasing Rogue One on Xbox.
