Hi there, we would love to help you on this matter. If you may have purchased the game without completing the steps above, we recommend processing a refund and then follow the steps on purchasing as a gift.
When making a purchase as a gift you want to ensure you click on buy for a friend, then complete the steps accordingly.
After doing so, your grandson will get an email containing a code with steps on how to retrieve the game.
Please let us know how this has helped you. If you require any further assistance please be sure to submit a support ticket and one of our awesome agents will be happy to help you.
