We are surprising our children on our middle son's bday in a few weeks with the news that they will be going to IoA to see HP in October. I'm just wondering, is there a great HP gift that would really spark his interest (and that's not too expensive...Target, Walmart, etc)?? The 2 older boys have already seen most of the movies and read the first book, and I want to get them all excited! And one more question...what gift card would you purchase for this visit? I'd like to get them all one so that I don't have to carry 3 wallets and keep track of money. I know the Universal gift cards don't work well at US. Thanks so much. Can't wait to make this a spectacular trip for everyone!!
