Being able to gift pre orders

Typically pre-orders aren't eligible for gifting. So it would be tied to your account and you wouldn't be able to gift it. You'd want to make sure it has the option to buy as a gift before doing so. Otherwise, if you gift it after it's been released, they will not receive the pre-order bonuses.

Once the game releases, you should be able to buy it as a gift. They just don't allow the gift option on pre-orders.

On another note...being able to get all of the pre-order bonuses without having to pre-order three copies of the game.

Yes, that's actually a brilliant idea. That should work. Just let him redeem the gift cards on the right account and he should be able to pre order that content using the gift cards.

You can't gift pre orders, unfortunately. You would have to pre order on his account. The only other option is wait for release date and then gift it.
