I purchased my preorder at Toys R Us, the day before presales were supposed to begin. I recieved my bonus disk at the same time. Did you actually go to the New York Pokémon Center, or did you just order the Colosseum preorder off of their site? Perhaps if you order off of their website, the T-Shirt and the bonus disk will be shipped to you with Colosseum. I really don't know how the NYPC does stuff, because I have never been there or bought anything off of their website. Perhaps you could give them a phone call, their telephone number is 1-877-4POKEMON. Or, you could try sending them an e-mail at customerservice@pokemoncenter.com
