I got my Game preorder confirmation and giftcard today. Basically come the 8th of December my Wii will be waiting for me, no queuing!
The giftcard is a nice idea, walk in, put money onto the card and it'll go towards the payment of the Wii. Handy to have somewhere to put the money so I don't end up spending it.
Also, on the 10th I can pick up my 'Preorder pack'. An info pack, nothing special but nice none the less.
