You should be able to purchase anything you want by calling the GM store's at the resort. We were at HH a few weeks ago and I bought some really great luggage tags. Upon coming home, I decided I needed more. I called sown there, they said no problem and sent them to me with no shipping charge!! The employee was also nice enough to tell me what "New" items came in.
He said this is standard policy throughout the Disney resorts...So just call for items and see if they will ship to you.
